Kossel Mini hexagonal heat bed holder

thingiverse

A modular framework for elevating a hexagonal heat bed on a Kossel Mini by some millimeters. Designed to fit perfectly with 15x15 extrusions of Kossels. Height and dimensions can be easily customized by adjusting variables in the OpenSCAD file. Note: The heat bed will be raised slightly, approximately 12mm, for sufficient clearance around large thermal fuses, the RAMPS LCD connector (RepRapDiscount Controller), and cork insulation. Print Settings: Rafts: No Resolution: 0.2mm layer thickness I printed this using Slic3r with 0.2mm layer thickness and a 0.5mm J-Head nozzle. Instructions: Note: Before installing your heating pcb, insulate its bottom to aid in faster heating up and protect your electronics and cables from heat damage. I used some 3mm thick cork. Important: Turn off power and remove the USB cable before working on your electronics. Be cautious not to fry your RAMPS by shorting contacts. Slice model and print three heat bed holders. Mount all heat bed holders with screws and nuts into position, but don't secure them yet. Center the front holder and slide the others to the back within aluminium extrusions. Install cables from heat bed. First insert pcb on its side with solder joints from thermistor into the front holder. Mount remaining 2x glass bed holders by sliding them in from the back onto pcb. Center all holders and place glass bed on top. Adjust glas bed brackets till glass bed is centered. Secure all screws.
