Anet A6/A8 Y Belt Holder Upgrade

thingiverse

Assembling the Anet A6 3D printer kit, I found that the Y Belt mounting was far too high for consistent belt tension. The belts included with the kit were thicker than standard GT-2 belts and much less flexible - I decided to replace them with standard RepRap GT-2 belts (available on eBay). The model is Prusa Style and comes in two versions, one for the kit belt and one for the thin RepRap belt (thin by name only). I replaced the screws with 2x M4 10mm and 2x M4 25mm. To tighten the belt, loosen the motor screws (or pulley), mount the belt loose, press the motor in place, and gently re-tighten the motor screws. Don't forget to leave a like or a tip if you find this helpful! Update: October 19, 2018 I added a Belt Holder for reinforced A6 Y-Belt-Holder-Thin-GT2_A6Ext+3_V2 with a 3mm higher base than Y-Belt-Holder-Thin-GT2_A6Ext_V2. Update: May 25, 2018 I added a Belt Holder for Gulfcoast Robotics Anet A8 A6 3D Printers Upgrade Y Carriage. The distance between holes is 28 mm instead of 20 mm on standard Anet A6/A8 Y Carriage. The model has PYP5 in the filename. Update: November 12, 2017 I added an A6 version with extended base (+4mm) for printers with greater distance from belt to y-carriage (A6Ext in filename). Update: October 28, 2017 I added a slimmer version for Anet A8 - Postfix A8 in filename. Update: June 13, 2017 I replaced the original model with a new version (V2) that has less height to give more room for the returning belt under the holder. The alignment is not perfect and the belt loops are smaller to make room for the lower profile.
