"Jar" for Simple Mason Jar Candy Machine

Nothing against Mason jars… we just didn't have one on hand. Decided to just create a printable one using FreeCAD and see how it turned out in clear PETG.

I printed in vase mode with 0.4mm nozzle, 0.8mm line width, 0.3mm layer height going very slow (~15-20mm/s) with no cooling. Used a single “concentric” bottom layer. It didn't come out super clear, but I suspect that's in part because I only dried the old roll of filament for a couple hours.

It just slides in place. There's nothing to lock it down (friction fit or threads). As drawn, it holds a 12 oz. carton of “Dubble Bubble,” though I don't see any reason you couldn't scale the z-height if you want more or less.

Thanks to Carl Belcher for a great model!
