Filament Scale Remix

I remixed Whity's Filament Scale to fit in my 40x60 mm prototype board. The board is mounted partially under the load cell, so I suggest soldering the arduino nano a bit closer to the outside wall.

I also moved back the screws for the micro USB PCB by 2.8 mm to make the micro USB PCBs I bought fit.

To remix the bottom part, I fully recreated it in OnShape. You can find my OnShape document here: OnShape Document.

Secondly, I modified the top part of the scale in Blender to fit a 15x21 mm switch that I already had.

And at last, I had the problem that the spacer block for some reason was not correctly positioned with the hole in the top part (which I only realized after soldering and assembling everything else).
I don't know if this is a problem with my bottom part design, my load cell or the original design. To work around this problem, I created a modified spacer with offset screw holes.

The parts I used:

• 15x21 mm KCD1 rocker switch
• Micro USB to DIP adapter PCB
