replacement part for scuba box

So I have a scuba box (https://www.obi.at/aufbewahrungsboxen/mehrzweckbox-scuba-mit-deckel-xl-110-l-schwarz/p/4894986) that I bought at the hardware store to provide a moisture-free storage to my filament.

While I'm still quite pleased with the box I managed to break one of the polypropylene closures. So here's a replacement lock.

It behaves a bit different than the original one but it's more stable and easier to lock.

I made it in two parts because that way it's easier to print and it also fits the more common 20x20mm printers. However you need 2 pc. of M3 screws + nuts to keep the parts together. Material-wise I can recommend printing it in PETG with 100% infill.

edit: edited the part (#16) to be printed in one single piece due to request.
