Tech drawer adapter for Ender 3 Pro Y-Axis Linear Rail Adapter

thingiverse

While installing a set of tech drawers (https://www.thingiverse.com/thing:3831119) into my Ender 3's front sections, I found that the linear rails on the Y-axis were just a few millimeters too low to clear the top of the drawer casing. After printing the drawers and casings, which was a long print, I decided instead to design these mods to push the linear rails upward to clear the drawers. These adapters will attach to either side of the rails and create screw holes 5 mm higher than standard V-slot holes. Each side requires one adapter, model 1, and another adapter, model 2, which are designed for bolts on either end of the linear rail. The adapters use M3 threaded inserts to retain the rails, making them easier to model than nut spaces. Since these adapters also push the rails outward by 5 mm from the Y extrusion, I modified the original carriage mounts to match. I thinned the mounts at the top and bottom to recover some lost Z-height and ensure the mount cleared the drawers, since the stock mount hangs below the bottom of the carriage. By thinning the top of the mount and compressing my bed springs a bit more, I believe I ultimately ended up losing only 1 mm or so of Z height. To use this adapter set, you will need: -8 M4x8 bolts and T-nuts to attach the adapters to the Y extrusion -4-12 M3x4 heated inserts and M3x8 bolts to attach the rails to the adapter -All hardware from the original kit
