Low profile Beamspring project

Hmm. Plastic actually not needed in this configuration - except for PCB protection. But if no plastic - some weight must be added to the bottom part, or all the beamspring fill's gone.

Would be fun to try different plate weights.

Im honestly impressed by amount of work you have put into this project. This is what we all wanna see. Keep it up!

Are you referring to the capacitive flyplate or some other component?
I'm planning to try different materials/thicknesses for many parts :)

Thanks! I finally got started with the CNC router this weekend so there'll be a proper update soon.
If anyone knows of reasonably priced sources of 15mm thick PA6/POM (nylon/delrin) please let me know.

I've been focusing on other projects recently and there hasn't been much progress, but here's a quick update:

I've finally got SKCL/M springs lined up, there were some unexpected delays.

I CNC'd and assembled the mold mentioned in a previous post. Still haven't cast any housings with it. I also have plenty of dowel pins and stainless m2 screws on the way so I can eventually cast more than one at a time.
I also CNC'd a 2x2 plate/lid and 4x2 housing block (wood, just proof of concept). I'm not sure exactly what material the white plastic is, but there's several m2 of it around, great for experiments :)

Finally, I found a source for reasonably priced 16mm thick POM which I plan to try out for housings and lids.
