This is a simple spindle holder for my nichrome wire spindle. I designed it in 2d and extruded it with OpenSCAD. Print out 2x side, 1x pipe. I added the DXF and SCAD files if you want to change something.To hold the pipe in place, you need a M5 square nut and a M5x20 screw on each side.Maybe add some rubber to it's feet or mount it somewhere so it will not move when you pull the wire.
