Poziomica ;)

The parts fit together quite well, but I recommend using glue.

If the mounting pins (part 4) prove to be too tight, use a 5 mm drill bit to drill out part 1 and part 2.

The set consists of:

Part 1 - 1 piece

Part 2 - 2 pieces

Part 3 - 1 piece of your choice

Part 4 - 4 pieces (print flat)
