PTFE (PC4-M10) Quick-Fitting Mod for Prusa Drybox

September 29, 2019
Description
I wanted to use the Prusa Dryboxes with a PTFE-Tubing clamp instead of the plastic-flap gap that the dryboxes currently use.
You don't even need to re-print the whole box! This piece simply attaches to the backside of the original drybox using the same screws (M3 8mm screws work perfectly for me.)
This piece is threaded for PC4-M10 quick-fittings for 4mm PTFE tubing (same stuff the prusa mk3s and most other printers use)
Here are a couple links of where you can get them, but you might want to search around in case these aren't the cheapest options anymore:

The gap that the filament goes through in the box is a little too narrow to fit PTFE tubing through, so you will need to use a drill to widen the correct spot a little.
To do this, attach this printed piece to the front of your box, and use the hole to line up where you drill into the box.
