Smartrapcore Alu - Rear L & R pulley holders/y rod supports fully supported

thingiverse

These are rear pulley holders for a SmartTrapCore alu printer, remixed from the original parts by SmartFriendz with my strengthening modifications to prevent splitting under belt tension. The design now includes fully supported pulleys that prevent twisting under belt tension by adding rigidity, which should prolong part life. This part is constantly under belt tension and increased force when the belt moves. The version of this printer I'm using features F608ZZ bearings instead of printed pulley sleeves, but they still fit. You can use your original M8 bolt. I've added experimental parts; if you print them and try them, let me know how it goes. The only change is adding lugs that slot into the 2020 frame on the sides, which should be fairly tight-fitting, so file them if needed. This design might also help prevent twisting under belt tension. Please note a fellow Reprap forum contributor has created an improved version of this design, offsetting the pulleys at http://www.thingiverse.com/thing:1678368, which seems very promising. Print Settings: Notes: Just print them strong ABS or PET/G works fine.
