Summary Simple and effective way to provide much needed lighting to any Hypercube. LEDs from amazon: https://www.amazon.com/gp/product/B017A26OU0/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 The glue on the back of the LEDs is junk, wont hold ANY weight. A bit of gel superglue does the trick. This bracket are press fitted to the 8020.net extrusions which have a 5.26mm channel. WILL NOT WORK on other extrusions that have a 6mm channel. The brackets have a 60 deg angle to provide as much light to the printed part at any height. Print Settings Printer: Hypercube Rafts: No Supports: No Resolution: .20 Infill: 20% Notes: no supports needed. 3 perimeters. Bracket not too thick so it can flex and not snap if you decide to remove it from the extrusions.
