Description
This is a modification of Airtripper's Extruder for NEMA 17 stepper with a planetary gearbox (21 mm hole spacing)
2 tube attachment versions are available:
-- M4 nut
-- M5 Pneumatic push-fit adapter
2 tube attachment versions are available:
-- M4 nut
-- M5 Pneumatic push-fit adapter
Instructions
I printed in PLA with a 0.5mm nozzle, 0.2mm layer height, 100% fill.
You need:
-- 2x M3x6
-- 3x M3x25
-- 2x M3 nut
-- 2x M3 washer
-- 2x M3x45
-- 2x spring or piece of rubber diesel pipe (see Airtripper's original)
-- M4 nut or M5 pneumatic push-fit adapter
Please note, this version doesn't use a support bearing yet - I didn't have a small enough bearing to fit the narrower hole spacing and 8mm gearbox shaft. I will upload a revision soon.
Updated: added a version for M5 pneumatic push-fit adapter

Great. I added a couple of reinforcements between the back screw holes and also the side filament entry point since that broke on my airtripper. I don't think it needs the top bearing. The shaft isn't long enough on my motor anyway.

Petr, many thanks. Would it be much work for you modding the airtripper/gearbox for using a pneufit (M5) instead of the M4 nut?
