Latest project - dope card holder

[scotton]

I've been doing some tweaking and tuning on a couple of guns so I wanted to use a dope card instead of printing elevation turrets. (I'll go back to the elevation turrets once I get everything finalized, I much prefer having the info on the turret).
I found a decent card holder with a picatinny base (Atlas Target Works) but the problem is most of my guns have a dovetail with a picatinny riser, and there either isn't enough room on the riser for the card holder or you have to remove the scope to attach the card holder. So I decided to modify the holder to fit on a dovetail.

Version 1 had a slot and recessed holes for an M3 nut and bolt. However, the slot was not big enough and the holder couldn't be tightened enough on the dovetail.

Version 2, I turned the slot into a cut, making the holder into 2 pieces. I also opened up the wedge that the card slots into so I can print a thin backer board to fit in the holder and use a binder clip to attach my dope sheet to the board. Or you could just stick an index card or business card in there.

I have it recessed to take a 25mm long M3 bolt because I have a bunch of those. It's easier to design recessed for the extra length of bolt than to cut the bolt.

Nice. Looks very functional with out being military looking. Good design.
