Hadron ORD Bot Foot and Screw

thingiverse

The foot design for the ORD Hadron BOT offers various advantages, including raising it to accommodate the power supply and housing two rubber inserts for stability on any flat surface. Printing without support is recommended to avoid cleaning up threads; M15x1.5 threads require a specific tap if not using this method. The 1/4" holes generally print well, and slight misalignment won't affect the rubber inserts' function. The foot's collar holds the printer's aluminum foot, protecting the threads from shear forces. Support material can be used with slic3r 098, setting overhang threshold to 29 for optimum results. A Torx T40 socket screw is designed for strength and can handle 5 Nm of torque before plastic shearing. Applying thread locker prevents the screw from loosening. Buna N 1/4" o-ring stock from McMaster can be cut to 10mm lengths and inserted with pliers. The foot assembly enhances the Hadron Bot's appearance, protects surfaces, and prevents wandering.
