Parametric version of mendel microswitch endstop holder, with most things changeable.Print out the STL file, attach to your axles with an M3 bolt, attach to your microswitches with screws, and hope that your printer will work better now you're not using tape. If needed, change the parameters of the SCAD file and recompile. Here are the current settings in SCAD file: bw = 5; // bracket width bh = 10; // bracket height cl = 15; // clamp length ad = 8; // axle diameter hd = 3; // bolt hole diameter nd = 6; // bolt nut diameter mhd = 2.5; // microswitch hole diameter ai = 0.75; // axle inset for clamp xw = 0.4; // extrude width mhs = 9.5; // microswitch hole separation bl = cl + ad / 2 + (bw - ai) + hd * 3 + mhs; // bracket length I didn't add a nut capture ala thing:30085, because I'm still trying to print simple things and I don't yet trust my printer's ability to print overhangs.
