The glass cover to the butter tray was victim to an unfortunate accident involving a 5yo. Luckily, dad has a 3D printer.
My butter tray has a deep inset with 20mm rounded corners. I whipped up the design in OnShape and printed with a 0.8mm nozzle (for the speedz) using some Hatchbox transparent PLA.
Feel free to print with more “normal” settings and a 0.4mm nozzle.
