Capacitance Substitution Box
Print Profile(3)
Bill of Materials
Description
This is a capacitance substitution box going from 100pF to 10 uF.
The switches are 2P2T from CW industries (GF-126-3011). They have a tapered ear. See CAD drawing picture. This taper allows for a nice compact clamping setup. I'm uploading a model for a resistance box as well.
We have 3 plates/profiles
- The box: printed with a 0.2mm nozzle and a carbon-fiber smooth plate from Elegoo on my P2S (no glue, just a clean plate). AFAIK Bambu does not have aesthetic plates for the P2S. In the resistance substitution box model there is a picture comparing the prints with the 0.2mm vs 0.4mm nozzles.
- The back plate: still uses the carbon-fiber plate, but a 0.4mm nozzle.
- The internal braces/clamps for the switches: uses a 0.4mm nozzle and a regular textured PEI plate.
There are 2 versions of the boxes. One is 2mm taller than the other. Which one you choose depends on how big your capacitors are and how tall you want the assembly to be.
