Top mount Airtripper for 5:1 geared nema 17 stepper by RatInDaHat May 8, 2013

Description

I made some changes to the AriTripper v3 extruder. I enalbled it to be mounted at the top of my mendel max. I also changed the m4 nut for a m4 rivet nut. Finally, i made it compatible with the 5:1 planetary geared stepper from robotshop. robotshop.com/geared-bipolar-stepper-motor-3v-233-oz-in.html

The only part that changed was the main body. everything else is the same.

I'm using the TL hobbed gear with 8mm ID as it fits the motor shaft.

If you want to mount two, i recommend printing the regular and mirrored version that i posted. Let me know if you have any questions.

printed at .25mm layer height, 30% infill, 2 shells, no support.

What are you using on the carriage hot end side?

ultibots, trinity, makers tool works, etc. for the geared stepper you need the 8mm shaft version, or to be able to drill it out to 8mm.

Is this still compatible with a nema17 motor without a planetary gear reduction?
