Printable versions of the Aluminium Spring Seats shown in the photo. Spring seats keep your springs seated and centered on rods (suspension) or bolts.I made a bunch of these for my Huxley's sprung print bed and as in the picture as part of the tensioning for the Wade Extruder.A trivial little thing that can make life a bunch easier. Looks better too.The scad file has parameters in the top so that the seats can be easily modified for any spring and rod/bolt combination.
