Old Uncle Dogmoth has something special for you today: Two extended versions of the level 2 retention strap, 150mm and 155mm in length, along with the original length if you just need a replacement. I needed something a bit larger for my optic, and after a bit of trial and error on FreeCAD, I got this working pretty well.
Printing Suggestion: The strap itself should be completely solid, however, I printed the bulged area around the single screw with 40% infill. ASA is recommended for UV resistance.
