Filament spool holder for 30-bot 3D printer
grabcad
The filament spool holder is designed for use above a 30-bot top bar (30mm width) and does not require threaded rods. It features a built-in filament guide to prevent unraveling and reduce mess. The holder consists of two parts, allowing flexibility in using different sized spools. For optimal printing, increase the scale by 4% due to PLA shrinkage, and only need support from the build plate. Version 1.3 updates include more allowance for bearing slots, ensuring free spinning after installation. Additional hardware required includes four M6 nuts and bolts, as well as four bearings (17mm diameter, 6mm inner radius) for smooth operation.
