Parametric Inverted Y Motor Mount for MendelMax

thingiverse

Introducing a replacement Y motor mount for Mendel Max printers, compatible with other aluminum extrusion frame printers after modifications. This part offers several advantages over stock components: it boasts full 4-hole mounting for increased strength; the motor can be attached using thermal tape or grease to enhance heat dissipation through the aluminum extrusion (as shown in the fourth image). Moreover, its inverted design transfers compressive stress onto support elements instead of layers prone to delamination. The part is fully parametric and comes with OpenSCAD source files for customization. The designer appreciates curved supports. Printing instructions include a warning against using PLA due to the motor's heat, recommending M3 screws for motor mounting, applying thermal tape or grease on the motor side for better heat transfer, and securing the assembly with M5 screws while adjusting belt tension as necessary. OpenSCAD editing requires specific configuration files from Prusa's i3 project found on GitHub, ensuring compatibility and ease of use.
