Printrbot Simple Metal - grip with spool holder

thingiverse

Printrbot Metal grip assembly requires spool holder. The spool holder accommodates spools with widths up to 90mm and internal diameters of 30mm. Instructions: To assemble, print the parts at a 40% infill level. Since no supports are required for printing, this step should not be necessary unless specifically needed by your slicer software. You can pre-emptively stretch the 7/16 inch heat shrink tubing with needle-nose pliers until it fits snugly over 12mm shafts. This is an optional preparation. Finally, attach the grip assembly using SHCS (socket head cap screws) and corresponding nuts. *While tightening these screws, be cautious to avoid restricting the z-axis movement of your Prusa or similar device
