Anti Rub feet for Santa Cruz Electronics BT30 tool holder rack on Tormach CNC mills

thingiverse

Santa Cruz Electronics sell a metal rack which fits Tormach CNC mills with enclosures, such as the Tormach 770M, 770MX, 1100M and 1100MX, and the rack is designed to hold a number of BT30 tool holders. It fits beautifully and screws to the top of the original enclosure, however, the bottom end rests against the paintwork and is not actually parallel. These two feet attach to the bottom of each side rail and do two things: 1) provide a plastic surface to avoid scratching the painted enclosure, and 2) keep the whole rack parallel with the sloping face of the enclosure so looks neat. I printed these two tiny feet in polycarbonate blend since this is fairly tough in a machine shop environment, but in fact any filament would be suitable in truth. The feet are left and right sided, and fit to the lowest screw, which becomes obvious when you see the rack assembled.
