Case for target stickers

For assembly, you need a screw with a half-round head and a cross groove of dimensions 2.5x25 mm. The black and white versions are mirror-inverted so that the tape faces the same direction.

If you want to have the cases connected by magnets, use 2x4x5 mm neodymium magnets.

I am also posting with source files for possible changes. Primarily intended for printing with PLA material.
