Robo3d Polycarbonate Plate Bed Clip

thingiverse

I designed these to hold a Polycarbonate Sheet (Lexan) on a Robo3d Printer heated bed. This stuff works awesome with no adhesives. I use only ABS and run the bed temp at 40c. You will get 100+ prints off of one $8 sheet. They may fit other printers as well. The sheet size is I bought comes from Home Depot and is 11x14x.093; you have to cut one inch off one side of the Sheet to make it fit the Robo3d printer. Print 4 of the large ones and two of the small ones. The four large ones go on each end of the build area (2 on each end). The 2 small ones go midway on the build area on the sides. They are small enough to clear the bearing screws. You could use all small ones if you had a 10x15 sheet cut (the actual size of the bed). You will also want to edit your startup Gcode for a polycarbonate sheet to autolevel BEFORE you heat the nozzle. Otherwise the hot end will dig into the build plate. Here's the code I use: G28; home all axes G1 Z5 F5000; lift Z by 5mm M565 Z-1; set the offset for auto-leveling mechanism G29; run auto-level G1 Z5 F5000; lift Z by 5mm M140 S[bed0_temperature]; Set Bed Temperature M190 S[bed0_temperature]; Wait for Bed Temperature M104 S[extruder0_temperature] T0; set extruder temperature. M109 S[extruder0_temperature] T0; set extruder temperature and wait for temp G92 E0; set extruder distance at zero G92 E0; reset extruder distance to zero Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: Doesn't Matter Supports: No Infill: 50-100%
