Top mount Airtripper for 5:1 geared nema 17 stepper
thingiverse
I modified the AriTripper v3 extruder by mounting it atop my Mendel Max printer. In place of a m4 nut, I installed a m4 rivet nut. Additionally, I made the extruder compatible with Phidgets' 5:1 planetary geared stepper (http://www.phidgets.com/products.php?category=23&product_id=3325_0). The only alteration was to the main body; all other components remained unchanged. I employed a TL hobbed gear with an 8mm ID that perfectly matches the motor shaft. For those looking to install two extruders, I suggest printing both the regular and mirrored versions I posted. If you have any queries, please do not hesitate to ask. The print settings for this project were a .25mm layer height, 30% infill, and two shells without support.
