Title: RMR mount shim
Post by: WobblyHand on August 15, 2024, 08:50:27 PM
It seems that for close range, I can't quite get my red dot and POI to line up.  More or less have run out of adjustment.  So I looked around and found that they sell an angled shim for this.  Of course, I didn't want to pony up the $14 they wanted, so I more or less duplicated it, with a reversible mount.  It's not fancy, but hey it's only sandwiched between the red dot and the mounting rail.  Designed a 1 degree wedge, starting at 0.2mm thick and ending up at 0.95mm thick.  Used 0.05mm layers to build up the height.  Didn't take long to print.  I'll check it out tomorrow.

Good job.
It beats pieces of paper or tape :)

Perfect job for 3D printing.

The holes for the posts (the outer ones) were a little snug, so I opened up the holes a wee bit.  Kind of hard to keep tight tolerance on FDM.  Reprinted it.

Here's the stl.  It's not a big file.  (214KB)  First layer should be printed at 0.2mm, all other successive layers at 0.05mm.  It's only 18 layers so it doesn't take long to print.  On a sample of one, using a Holosun 507C, I could make it work.  Hope it is useful to someone.
