M5 T-nut for 2040mm aluminum extrusions

thingiverse

As I rapidly ran low on square nuts during my AM8 frame construction, I hastily fabricated these makeshift replacements to hold the control panel in place at the front of the frame. I wouldn't recommend utilizing these for securing anything that demands firm retention, as they tend to strip out easily. In the near future, I plan to replace them with authentic nuts. You can thread a nut into the unthreaded hole, but it will deform the nut and secure it firmly in place. I used an M5 tap to carefully tap them. To prepare the nut for insertion, I run it upside down along the slot to smooth out the raised portion of the nut before inserting it into the rail and repeatedly running it along it until the nut moves more smoothly within the slot.
