About this 3D model
Yet another spool support. It clamps on to the top of an i2 Mendel and is pretty solid. The SCAD file is set up for a 2cm spindle - I'm using a length of clothes rail - but is easy to change to suit what you've got. It clamps on with 2 M3 bolts per support, and has nut traps to receive them. If you're printing a pair, and why wouldn't you? You'll want 4 bolts, 4 nuts, and optionally, 4 washers.
