Holder for Black & Decker 20V Lithium Ion Battery

This is my remix of fdavies' battery holder that accepts Black & Decker Lithium Ion 20V batteries. My application calls for it to be attached differently, to wit, inside a box and attached to the bottom and one side. I determined the only reason the original version needed to be printed with supports is the "catch bar" part that engages the retention mechanism on the battery, so I worked out a way to print it separately and secure it with the same screws that hold the unit to the side of the box. It would be pretty easy to put in holes similar to those side-mount holes near the other end and remove the flanges, allowing you to attach this unit with screws going in a single direction, but I don't need that so I have not done so.

Revised 1/3/22: After printing one of these, I realized neither my design nor the original provides any way to get the wires "out" of the frame if it's screwed down to a surface. All openings are blocked by the battery. I'm assuming the original version was installed on a surface with holes in it for the wires to pass through, but that's not how I'm using it. So I've uploaded an R6 version which has holes in the sides for the wires to go through (with enough room for two fairly heavy wires to pass through one hole if needed). I changed the mounting holes to all go the same way, as I also discovered that screwing it down as I originally planned will prevent the battery from seating fully. Gah.

I'm leaving the R4 FreeCAD file as well as the original R4 STL of the holder frame for anyone who can make use of them. I did remove the R4 catch bar since I shaved the bevel ever so slightly to improve the fit, and the R6 catch bar should work fine with either R4 or R6 holder frames.

Revised 7/6/22: I've added an R7 holder frame which has the countersunk screw holes of the R6 frame, but is designed to mount vertically like the R4 holder frame with an added spacer on the end to give clearance for the bulk of the battery.  This holder frame is also, of course, compatible with the R6 catch bar.
