Prusa i3 Steel base mount
thingiverse
The Prusa i3 steel frame, especially the one with the 200 x 300 mm base that I have, isn't especially rigid especially laterally with both ends of the base being capable of being moved from side to side. To increase the rigidity of the base I mounted the entire printer to an 18 mm MDF base with six of these feet, 2 each at each end and 1 on each side one the back side of the Z stepper motor mounts. I made mine out of ABS but I guess PLA would work just as well. Print Settings Printer: Prusa i3 Steel 200 x 300 mm bed Rafts: No Supports: No Resolution: 0.2 mm Infill: 100% Notes: I printed mine with the foot on the bed in the same orientation as you would use to mount the bed, i.e. with the slotted hole for the woodscrew downward on the printer platen.
