When re-doing and enlarging my attic hatch, I wanted a way to hold the relatively light hatch panel (1/2" plywood with 6" of rigid insulation foam on top) down tightly against the hatch opening/trim it sits on, as to create an airtight seal.
So, I put some weather stripping around the border of the hatch, then designed these clamps to hold it shut tight to hopefully make my leaky house a tiny bit less leaky.
All PLA. For the make and female arts:
5 perimeter layers
30% gyroid infill
For the washers:
10 perimeter layers
50% gyroid infill
I had the make the washers stronger, because the first test started to bend/deflect a bit too much when I tightened it down a little bit.
