This is a upgrade mod to eliminate the front and back y-frame plates along with the cheap idler bracket and wimpy y-motor bracket. This mod gives you stronger y motor bracket and a better idler tension . Also changes the belt path to be perfectly aligned and closer to the bed. And the y motor now sits outside of the frame area making it easier to align your belt. there are 2 mod versions to choose from. 1 - azza z brace version with both types of feet. 2 - SWD2 rear mounted z brace. I only uploaded the parts i modded and created. The rest of the parts for the z braces can be found here: azza z brace: https://www.thingiverse.com/thing:921948 SWD2 rear z brace: https://www.thingiverse.com/thing:2391089 B.O.M-- 2020 Y frame upgrade Hardware needed: 2x-- 180mm 2020 extrusions 22x-- M5x6mm or M5x8mm 22x-- M5 tnut 5x-- M5x20mm ( 2 for belt guide-- 2 for bed belt bracket-- 1 for idle tensioner ) 5x-- M5 nut ( 2 for belt guide-- 2 for bed belt bracket-- 1 for idle tensioner ) 2x-- M4x10mm (for bed belt bracket ) -- (M4x8mm should work for stock y plate ) 2x-- M4 nut (for bed belt bracket ) 1x-- 8mmx40mm rod (or cut 40mm off a M8 bolt ) 1x-- M3x16mm (for idle tensioner ) 1x-- M3 nut (for idle tensioner ) 2x-- M3 set screws (to lock down the m8x40mm rod for idle tensioner ) 4x-- set screws to lock down y rods ( use original ones from your 3D printer ) 4x-- M3x6mm ( for Y stepper motor ) 6x-- Ball Bearing 625 2RS 5x16x5 ( 4 for belt guide-- 2 for idle tensioner ) 6x-- 1mm Precision Shim ( 4 for belt guide-- 2 for idle tensioner ) 1x-- new GT2 belt (For new stepper motor position and belt routing)
