Hadron ORD Bot Foot and Screw

thingiverse

I came up with this simple foot design for the ORD Hadron BOT. This actually solves several issues, namely: Elevate the BOT to provide room for the power supply House two rubber inserts to provide solid footing on any flat surface Instructions The foot is printed without support. I recommend printing it without support, because otherwise you'll have to clean up the threads. These are M15x1.5 so if you don't have a tap for it, it'll be pretty tedious. The 1/4" holes usually print ok, and since they'll house rubber inserts some out of true position will not heart them. The collar of the foot holds the printer's aluminum foot so the threads are not being subjected to shear. If you want to print it with support use slic3r 098 and @ the support material options set the overhand threshold to 29 (the standard metric thread has a 60 deg. profile) The foot and the mating screw should have enough clearance, so you'll be able to assemble them using no additional tools. I designed the screw with torx T40 socket rather than with hex (Allen wrench) because with this it'll be the strongest. I tested it, and it'll carry 5 Nm of torque before the torx bit will shear the plastic. I add a dab of thread locker to prevent the screw from loosening. I ordered some o-ring stock from McMaster (Buna N 1/4" o ring stock). I cut 10mm long pieces and insert them into the hole with a help of a set of pliers. The foot assembly will improve the Hadron Bot look, and prevent it from damaging the table it is resting on, also it'll prevent the printer to wonder away. see more details @ my blog here: http://www.buildlog.net/forum/viewtopic.php?f=33&t=1567&start=230#p21481
