Comgrow Filament Driver Shim

This is a shim for the dual filament dryer from Comgrow (see picture).  It should also work for Sunlu as I believe it's the same dryer with a different badge.

This allows moisture to escape from the box to help dry the filament.

There are holes for inserting PTFE tube to use it while printing.  These are at a better angle than the ones included on the box.  You can orient them in either direction depending on whether your dryer is above or below your feed.

I printed at 0.15 with no supports.  Only needs a brim if you have adhesion issues.  Depending on the tolerances of your printer you may need to grow or shrink slightly for the tube fittings.
