Well… This time something really huge - AR-61 Tenderizer from Helldivers 2. Over 1 meter od democracy!

Whole model at 100% scale, 5% infill and 3 wall loops takes about 2kg of filament so please be aware of it. I didn't test that option, but 80% of scale and 2 wall loops should save a lot of time and material with no big impact to final effect. You can use both - 12mm diameter rods or attached plastic connectors (plate 12 and 16, you'll need about 20 long parts).

Modeling, testing prints and fitting all the parts took me much longer I would like, but I think I can finally share my work with everyone :)

This model is uploaded as it is - every single part was created to build my own version of that rife from scratch. I can only assure you that I printed each part at least twice using PLA and managed to assemble everything.
If you have any idea or suggestion - let me know, I'll try to help or tweak model.
