Stopper for OTT adjustment 3mm Bolt

Calling it a remix as it's basically the same design, but I did not use the stl file from the original as a base so there are some differences.

In function it's the same as the original design, but the tightening bolt is now an M3x12 Flathead.The reason for this is that I am lazy and didn't feel like going to the store for an M2 bolt. Also sometimes it can be a pain to find M2 hardware.

For printing I went with 0.1mm layers and PETG filament.

Some notes:
This is a tighter fit. The outer hex has an interior dimension of 18mm on most printers this will make the interior less than 18mm. So it is recommended that you put this on the OTT adjuster before putting the bolt through. Otherwise you will most likely break off the 5mm internal hex.

Requires:
1x M3x12 Flat head bolt
1x M3 nut
