Holosun 507 Comp Cover with lanyard hole

thingiverse

Update: added a different model which puts the lanyard hole on the right side because the original one may not fit if you have a rear iron sight. Also slightly reduced wall thickness in the back to fit better into the gap between the optics and the iron sight.Based on alokin79's model. I added a lanyard hole so I can attach a flag or something, making it easier to stow the cover in pocket temporarily when I remove it to shoot.Printed mine with TPU with its natural orientation (opening facing down) with supports, so I could iron the top layers. Or print it upside down, which would save some material and make it easier to remove the support. It's a snug fit. If you print with non-flex material you may want to scale up a little bit. And you may be able to print with the orientation came in the model without support, but I haven't tried.
