In the spirit of those Fastcap guide rail holders that let you attach your tracksaw tracks to your garage door, this lets you do that with your TSO parallel guides.

Onshape source here.

An overhaul of this TSO holder: https://www.thingiverse.com/thing:5240409

Hardware required:

  • Countersunk metal screws - Jeez I forget what I actually used here but you probably want around 3/4" / 18mm long #10 or #8 (SAE) (Canadian living in America...) if you have an insulated garage door. This will work for both the bottom and top screw. The bottom screw will protrude deeper as the model is only around 3mm thick at that point.
  • A 20mm m4 socket bolted screw with 0.7mm (standard coarse) thread pitch to attach the handle to the base.

I changed a few things in the original model that I thought impacted the usability:

  • The handle in the original model really could use a chamfer to help ease it into a compression against the TSO guide when it's rotated onto the guide. The original model required quite a bit of force to rotate the handle into place as it encountered the sharp edges of the TSO guide. The chamfer is at 60 degrees and should print great without supports in the default orientation of the model.
  • The original model lacked fillets and was prone to cracking along sharp corners.
  • I've added a notch to the "handle" so that you can screw the "base" in without having to first remove the "handle" portion when using countersunk screws. It's nice to assemble before taking it to the garage for mounting.

I printed at 0.2mm on a Bambulab X1C in PLA.

There is enough interference fit that the 'base' will click to the TSO guide without the handle rotated into place, but it does not cause deformation of PLA. I iterated about 6 times to arrive at a nice tight fit here :)

The TSO guide face protrudes about 0.3mm in front of the printed base - this is deliberate in order to get a nice tight fit once the handle is rotated into place. The chamfer on the underside of the handle helps coax things into place.

The handle attaches to the base using an m4 bolt with a 0.7mm pitch (standard for the size). IIRC 20mm length will work. The base itself though has a thread printed and this is where the friction is intended to come from.
