Filament Pass-through fitting for lack top with fluted end for PC4-M6 fitting

thingiverse

I saw some filament pass-thru fittings but they wouldn't accept a Capricorn Bowden tube PC4-M6 fitting so I designed my own. you can use them to pass through lack table top or legs for a clean safe pass thru. the end is beveled to not cut the filament. You can run your filament in one end and straight into the capricorn fitting to the bowden ptfe tube. I did it to run from my top filament box to my direct drive extruder hot-end combo because I was wanting to protect the filament the whole path. It hasn't negatively effected my prints at all. you still have to thread carefully the fitting into the end. if it is too tight, just scale it up as needed in your slicer.
