This is my first real creation in TinkerCAD, where I tediously added chamfers and fillets before I started using software like Fusion.

Little containers pictured on the right are the first iterations on our very limited first printer.

The square boxes stack on top of the circles.

These two shapes have been my most useful ones in the house, and they were previously shared on Toybox but I'm sharing them here now.

I have since upgraded my hardware and have needed a larger container to hold pens and such.

Caveat, they have my childrens initials, a logo I designed in TinkerCAD stamped on the bottom.

For the current large version, I went back in and manually extended certain parts in TinkerCAD, added additional ribbing, kept the same wall widths as the minis.

Standard printer settings should work fine.  I used, 0.4 nozzle, 0.2 layer, 2 walls, 20% infill gyroid, 5 top/4 bot.
