Clamshell Parts Box

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.

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 tall, 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.

Organizing

Okay, so now you have 4, or 10, or 100 clamshell boxes, and you need a way to store them. What are your options?

Wall mount rack

Available here, these racks are efficient in filament usage and print time, mount using standard wood screws, and tile neatly with different sizes of box.

Racks - freestanding or multiboard mount

Available here, these racks come in variants that hold from 3 to 21 clamshell boxes, and come in freestanding and multiboard mount options. Put a few on your desk, or cover your entire wall with them!

Gridfinity Bins

These storage trays come in various sizes and let you stow your boxes in your gridfinity setup. They come in stacking and non-stacking varieties.

This design by TheMightyPong is particularly compact and fits 3 boxes in a 2x2 Gridfinity space.

Alternative wall-mount racks

This wall-mount rack by Chris Be accommodates 4 standard boxes, and screws directly to the wall via screw holes hidden at the back.

This one by loki21 mounts to Ikea Skadis.

Lightweight Trays

These trays by MKdesign accommodate standard boxes and use only a few grams of filament. They can be snapped together for larger storage arrays, as well as stacked vertically.
