Printer Shock Absorbers

These are spring-based shock absorbers for any 3D printer, to dampen the torque generated by the motors. This reduces vibrations and overall noise.

The base clips will work with any printer, just print your printer's feet with screw holes to fit the base cap. Included here are STLs for the Printrbot Simple Metal 1403 feet.

The caps come with short pegs to hold the extruder springs, and have free play to avoid stress damage.

This design allows 360 degree movement and I no longer feel or hear the vibrations I used to get on the table. I've kept the old foam mat until I have time to get some nice fitting rubber feet.
