Ballbearing Lock for Orbiter Extruder Dual Drive Extruder

thingiverse

Hello everyone! (ツ)╯ I designed this lock with a ballbearing (Fig. (A, 2)) for the Orbiter Dual Drive gear extruder (Fig. (A, 1)). You can also use it as a reference for spare parts of this particular extruder. Printing: The holder can printed without any support. It is recommended though to print the bottom holder with a 45 DEG angle, as illustrated in Fig. (C). Full print with 4x4x4 walls/top/bottom and 38% infil came to about 48g in weight. Glue in lettering and spade. Star may need minor sanding but should push fit into the space tightly and not need anything else to secure it.
