During my internship, the CEO of the company gave me the opportunity to design a bathtub for him. This was a good exercise to strengthen my CAD surface modeling skills.

The unique result that I created can been seen underneath. Before it was built, a scaled version of the bathtub was 3D printed. Interestingly, he employed a boatmaker to build the tub. Unfortunately, I do not have many images of the desing process.

Mats Erdkamp came to me with a commission to think of a way to implement a special button for his FBP. Interaction with the button, one should be able to rotate, press, press up and press down the button. Meanwhile, the button should also feature a screen. I successfully puzzled a design together where all these things are possible and 3D printed it.

I once got an MRI taken of my brain. After going through the MRI, you get the files on a CD.

After multiple Freesurfer runs (10+ hours in a Virtual Linux Machine), only of which my last try succeeded, I had a 3d model. I could not have done it without the help of this tutorial.

Once I had the 3d model, I could start with my own design. The most complex part was merging both brain sides and inserting a hole for the lamp. The object was never manifold in the end. After a lot of puzzling, it finally worked. I designed the stand so it looks somewhat like a brainstem. Preparing it for printing was rather time consuming because it needed support, but not in the smaller creases of the brain where I could not remove it. I had to do every crease manually using cubes as excluders for support. Next time, I will try to make this a more automated process.

I decided to print it in clear transparent PETG because that would let through the most light. The 3d print failed halfway but I was able to continue where it left off by modifying the GCODE. I decided to make the stand red because it was the most contrasting color I had.

I plan to reshoot the pictures because they do not reflect the actual (in my eyes great) aesthetic of the product.

This was a birthdaypresent for my mother. This design is best left undescribed.

This is definitely my most extensive design until now with lots of iterations. This is going to be a long story.

I bought a diamond sharpening stone. I am fascinated with this stone. It is the only thing you need to keep your knives sharp. It also lasts for a VERY long time. I am fascinated with sharpening in general because it saves you a lot of frustation with dull knives, saves you money and saves the environment. I see a lot of people throwing cheap knives away because they are not sharp. That is honestly a waste since you have more than 99% of the metal left. Cheap knives can be as sharp as expensive knives and can last for a long time.

Although, you can sharpen 'freehand', you can get even sharper knives when using a sharpening system. However, these systems are notorious for being expensive. Luckily there a multiple 3d printable models on the internet. That was my initial plan until I saw how much different parts and screws they required. That is why I set out to create to create a easier to make sharpening system.

This is my first iteration. Only one screw thread was required and two screws. Did it work well and was it easy to use? No. The screwthread was to rough to move easily back and forth when doing the sharpening motion. Adjusting height took too long. The screws ripped through their plastic holes when fastening the knife. It felt flimsy overall. However, it was a very simple design.

Second iteration. This design uses aluminium tubes that can slide more easily. Everything is now fastened with screws and bolts so the plastic does not wear when holding the force. The height adjuster is now angled so it can support every viable height.

When speaking to a sharpening entheusiast I found that so would not use it to sharpen expensive knives because the screws might scratch the knives. It is also rather dangerous to use because the design needs to be used on the edge on the table and the knife might fall down.

At this point I reaslised that this design would not work out. I decided to design a 'good' sharpening system using my knowledge from the previous design. This time, I would allow myself to use more parts and screw etcetera.

Iteration three. This design is sturdy and allows for a fast workflow. It only has some parts and requires some screws and accesories but not too much.

The knife is held by a spring and does not touch any metal. The block that holds the knife steady slides on two aluminium tubes. The roundness in the block allows for different knife shapes. The two little blocks that touch the cutting edge of the knife are replacable. This way of holding the knife ensures that the cutting edge is always in the same place. Once the angle is adjusted, it can be used for every part of the knife for different knives because the angle will stay the same.

The height adjustemnt part has become more sturdy as well, being held by two tubes. The part is fastened to the tube by clamping the plastic around the tube and not pressing a screw onto the tube which might damage it. The rotating part is inserted easily but when the tube is inserted, it cannot come loose.

I bought a good microphone. It did not come with a stand so I designed and printed one. As far as I am aware, there are no online 3d models that are are adjustable in height. This was the most important feature for me. I also should not have a surface area. I used my knowledge from the flashlight engraving holder to design the thread to achieve this. Most microphones come with the same 5/8 inch thread hole including the two microphones I have so I made a 5/8 inch thread to fit the microphone. This makes the stand quite universal.

The first iteration did not turn out that well. The weight of the microphone bent the stand. The microphone broke the stand. The microphone in the picture is a lighter microphone that does not break the stand.

This is my second iteration. The stand now features an more efficient and stronger shape that does not require too much material. The stand now is the screwhole and the extension is the screw which gives it a nicer look. I also added 2x2 holes to the stand for future clips that might hold the cable. In the end, this turned out not to be necessary.

I use this design almost every day for either university meetings or gaming with friends. I have not found any downsides to this design execpt that is has no dampening/shock absorber and no pop filter.

This is a very specific print that I did for a company. This company engraves a lot of flashlights. They were unhappy with their own method (see the wooden block in the first picture) so I designed and 3d printed a new one. The problem with flashlights is that they have no flat surface area (like knives) and easily move. Another problem is that the diameter of the head is not equal to the diameter of the back. This results in a height difference. Underneath you can see my first iteration that features one leg. It can be adjusted in height. One side of the flashlight is placed on the device and the other side is place on a support of choice.

This is my second iteration. Now the whole flashlight is held by the same device. This mechanism might seem unnecessarily complex. However, it ensures perfect precision. You can also adjust horizontal lenght for flashlights of different lengths. This also helps the engraver to engrave the flashlight on exactly the same place when doing batches of the same flashlight.

I think this was a succesful design. I had no reference exept for the wooden block. I fully designed and printed it myself.

I 3d printed a prototype for an Industial Design project for a friend. I had some doubts if it would work but in the end, he and his project group managed to assemble it succesfully.

Transmission Ticker

Modern cars come with modern keys, namely NFC/RFID cards. We are used to carry our car's (remote) keys around but not cards. It is easy to carry around cards in your wallet if you are the only one using the car. However, when using it with multiple people this is far from ideal. In addition new vehicle insurance and ownership document also come in creditcard form. Because card keys are a feature mostly made for electric cars, you often also have a charging token that you would normally hang on a keychain.

I designed a card holder specifically targeted at this use case. It is an open design so you can view the information on the cards without removing them from the holder. This design also makes it very difficult for the cards to fall out. It has a loop to attach a charging token to it. However, one user also used it to attach the holder to his/her lanyard.

This is also the user that also requested a 'privacy side' that lets you cover certain information. For example, not everyone should know what car you are driving. I know have a design with a privacy side and one without. Both designs will be printed in PETG for flexibility, strength and durability.

You might say I borrowed the idea from Makers Muse... Yeah, that's true.

I was inspired by Signify during an University Industrial Design project. I did not print this myself but it was a huge inspiration.

These are some of the models that I designed and printed using transparent PETG. Transparent PETG is a great material for printing lampshades. It's flexible, strong and just transparent enough to create beatiful lighting. I used a Yeelight to provide some RGB light.

Here I tried to create an interesting beatiful shape.

Here I actually succeeded to create an interesting and beatiful shape.

This is just a case design to house electronics for a project I did at the university.

My first 'print in place' design. This means that the entire model was printed in one print cycle. The bowl can rotate inside the frame.

This is my first design. I created this toothbrush holder because the body of the toothbrush smutted the sink.

After I printed and used it, I was happy to find out that it also stopped the toothbrush from falling over.

Of course, a benchy needed to be printed.

Wikipedia: "The 3DBenchy is a 3D computer model specifically designed for testing the accuracy and capabilities of 3D printers. The 3DBenchy is described by its creator, Creative Tools, as 'the jolly 3D printing torture-test' and was released in April 2015, with a multi-part, multi-color model released in July 2015."

This is where it all started. The model that came preloaded with the 3d printer. It failed in the very end.

I put the printer in the basement because it produces a lot of noise.

I also added a ventilation system because 3d printers tend to create questionable fumes.
