25mm Aluminum Extrusion Delta Printer Brackets

thingiverse

These are corner brackets designed for joining together 80-20 25mm aluminum extrusions used in building a delta 3D printer. The bottom bracket includes holes for mounting an NEMA 17 Stepper motor and space for installing a G2 belt adaptor. For the top bracket, there is a mounting spot for two flanged M3 bearings serving as an idler pulley for a 6mm belt. A 40mm M3 machine screw is required to secure the bearings. Additionally, the brackets feature a place for connecting an endstop switch; links to both components can be found below. http://www.thingiverse.com/thing:1266969 M3 flanged ball bearings are required for construction; find them at http://www.ebay.com/itm/F623zz-Mini-Metal-Double-Shielded-Flanged-Ball-Bearings-3mm-10mm-4mm-/141338763495.

With over a year of design and thousands of hours spent fine-tuning this machine, I'm almost ready to release my new version. Visit http://www.dimension3fab.com for updates. **Print Settings** **Printer**: Custom Delta 3D Printer * Rafts: No need * Supports: Use supports for secure prints * Resolution: Medium (0.2) * Infill Density: Moderate (50%) Tips: Make sure the model adheres to your printer during the printing process. Post-print cleaning and securing steps are also critical. First, clean up any support materials left on the print, ensuring there's nothing hindering performance. Then, ensure secure bolting by carefully sliding hex bolts through extrusions until rigidly secured using matching nuts.
