Bit box 70 x 50 mm, pin hinge, no latch
A one-piece box for a driver bit box that opens with one thumb: base and lid print side by side, joined by the hinge, and fold shut straight off the bed. The pin hinge wears in after a few folds and lasts hundreds of cycles. No latch, so it flips open with one thumb.
