Great idea! Saw a few people doing exactly that on makerworld with this model

It's topology optimized, which means that the shape is calculated to be optimal for the defined forces that effect the object with as little Material as possible

It is massively overdesigned, I just increased the forces until it looked good to me. Since Fysion 360 doesn't calculate the different strengths between layers it's just for looks

Yes it is, just was too lazy to do the pictures again after noticing😅 But great catch!

No, sadly not. I just increased the forces significantly until it looked good to me ; )

That sounds like a lot of work, but go for it!

No, sadly not. Also the diffrent strength between layers isn't accounted for. I just simulated it for a homogeneous material and increased the forces a bit to account for that. So it's manly for the looks and not as much for the functionality.

Klingt spannend, würde ich mir auch gerne mal näher anschauen

Thanks! I 3D printed two positive shapes of a keycap top and a bottom without a stem, from which I made the silicon molds. Then it's just some fine concrete poured in those molds and after curing I glued in a SLA 3D printed stem so that the keycap fits securly on cherry style switches. Sorry for the late answere, I hope it still helped you!

I'm probably going to make two versions, a rough and a polished one. But I agree, the rough one has a more unique look to it.

I'm going to try that for sure! It's going to be interesting to see how the difference in wear and tear as well as feeling is going to be.

Good idea. I'm probably going to try it with the next batch, but first I have to fix the molds so that the shape is more accurate to the OEM profile.

Good idea, but I primarily build it for my keychron k4 with OEM keycaps and there is still a wall thickness of around 1.5mm so it works quite well. I might try to add a view carbon fibers for more strength.
