Designed to fit neatly into this awesome wall https://www.thingiverse.com/thing:2194730 by Snowman77. It is exactly the length of 4 of his long straight wall segments so you can keep your wall length nice and symmetrical.

The swing arm is a print-in-place hinge with both .2mm and .4mm clearance options. You can also put up a sign to let all the baddies know whats up.

I placed 3mmx1mm holes on each side to insert magnets. I recommend using magnets or something to give the swing arm more steadiness since it will fall over easily when lifted up.

If you print the shack in 3 pieces then you shouldn't need a single piece of support for anything here, especially not for the swing arm.

Any constructive criticism is welcome! Enjoy.
