Description

I wanted to mount some cables to my Prusa MINI's Z alu profile using something reusable - that's how this rachet was born.

The "T-nut ratchet for 30 mm alu extrusion profile.stl" contains a pocket for an M3 nut. You can fix it with a 15 mm M3 bolt.

I have iterated a simplier version with an M4 hole to use it with a proper T-nut.

Update #20200211 - new features:

  • t-nut turns only one way
  • ejector hole for the M3 nut
  • countersunk slot for the M3 bolt
  • more room for the hex key / screwdriver
  • extra teeth for tighter lock
  • smaller and 60° teeth for easier operation
  • left side of the rachet will not overhang on the 30x30 profile hence allows easier installation even if something is already installed on the side of the profile
