Lakeshore Trace & Draw Projector Slide Case

Here's a neat way to organize the slide disks for a Lakeshore Trace and Dray Projector toy, it has 10 slots that easily hold 1 or 2 disks for up to 20 total. I've fixed the screw and hinge issues called out in the comments and this now prints as 4 pieces, using 3 25mm M3 screws for the hinges and latch.
