regular hinge for the penguin box

I designed a regular single-pivot hinge piece that works with the penguin box.

I found the standard dual-pivot hinge to be not very practical in daily use so here is an alternative hinge, that uses an extra M3 bolt (M3x12 w/o a nut or M3x16 with a locking nut).

The hinge consists of two pieces (within one .stl file) and can be printed in place. You can also split the hinge in your splicer and separate the hinge before printing.

Make sure to align the parts so the side that goes against the penguin box is flat on your printing bed.

Some supports are needed.

I created a tight and a looser version - pick the correct one depending on the seal option that you chose for your penguin box.
