I love the form factor and size of Josh-3D's Small Parts Storage Box, but I really wanted something that doesn't separate into two parts - and so the Clamshell Parts Box was born! The perfect size for storing small hardware such as bolts, screws and bearings, these boxes print-in-place with a robust and functional hinge, use only 33g of filament, require no supports, and print in under an hour! Space is provided on the front of each box for a 40x14mm label. A small catch holds the lid in place when closed, and they can be stored flat or standing on their hinge thanks to the included feet. A gridfinity storage tray is also available. I've designed the standard box to the same dimensions as Josh's model, 70x70x25mm, so they will also fit in existing organiser trays. For smaller items, variants with the internal space divided into two or three compartments are available. For storing larger items, extra wide and extra wide extra tall variants are available, along with gridfinity trays for them. These are not the same size as Josh's extra large variants for ergonomic reasons - I found 140mm was simply too wide to comfortably hold to open. The boxes print fine in standard PLA, though they work even better in PETG. I don't recommend matte or silk PLA. A transparent profile is also available, which takes significantly longer but produces translucent prints that allow some visibility into the box's contents.
