Pica Dry Color Caps

This is a color cap for the lead fill on the Pica Dry Automatic pencil.  These are useful for indicating the lead color loaded into the pencil.

The stores near me stock the pencil but not the color caps, so I made this one.

This relies on a friction fit so your printer should be well calibrated.  I provided a few options for different print tolerances. The 0.15mm version worked well for me.  A lower number will make a tighter fit.

You can also change the fit by changing the “Tolerance” parameter in Fusion 360.  As before a lower number will make a tighter fit.
