This is a dual tube quarter holder I designed to hold $20 worth of US quarters for coin laundry when out of town. I printed in PETG at .20 layer height. No supports are needed.
The lid is held on to the body with two short sections of filament. I heated a small flathead screwdriver with a torch and flattened the ends of filament so they don't slide out. It is a tight fit for the 1.75 filament to go through, but with slight pressure and twisting, it should slide right in. Start with a longer piece then needed, flatten one end and trim with some snips then flatten the other side.
In short time of testing, the locking tab seems to hold up just fine, but I can beef it up a bit if anyone has issues.
*Color used in this print is Prusament Carmine Red PETG
