Bearing Retainer PLUS Plunger Screw Adapter
thingiverse
This is an upgrade and modification of Emmett's bearing retainer, inspired by Johnboiles'. The main goal was to improve visibility in the plunger/bearing/filament feed area for MK5/MK6/MK6+ stepper acrylic faces. Material was trimmed while maintaining rigidity, with standoffs borrowed from Johnboiles' design. A new feature addresses the issue of loosening plunger screws by incorporating an arm that fits snugly around the shaft. The latest version 7 offers additional support under the plunger screw and enhanced viewing area. Print the thing, remove the existing nuts and bolts, insert four M3x16 bolts, reinsert the plunger screw, and enjoy worry-free, extended printing sessions!
