Single-piece toothpaste tube squeezer — also works for any soft cosmetic / cream / paint tube with a folded crimp at the empty end.
Use:
Slip the empty (crimp) end of the tube through the slot.
Fold the crimp back once around the squeezer body.
Twist the body — the tube wraps around the 15 × 5 mm bar (~36 mm of tube consumed per full turn) and gets squeezed uniformly toward the cap. No more wasted toothpaste at the bottom of the tube.
Sized for full-size tubes — slot is 50 × 1.1 mm, fitting any standard toothpaste / cosmetic tube crimp (up to ~48 mm wide). The 1.1 mm slot height grips the folded crimp firmly so the tube can't slip back when the body is twisted to crank the squeeze. Smaller travel tubes also work; the slot is just under-filled.
Diamond-knurl grip: both faces are engraved with crossed diagonal grooves at ±45° — industrial-tool aesthetic, gives the fingers something to bite when twisting.
Top face: 0.5 mm deep grooves (clean visual relief)
Bottom face: 0.3 mm deep grooves (= 1–2 layers, shallow enough that first-layer adhesion stays solid — first-layer line is 80% contact, 20% groove, well within elephant-foot tolerance)
Hang hole at the top so it lives on a hook above the sink.
Print: flat on the bed, no supports, single colour, single STL. The .scad is parametric — body_w / body_h / body_t plus slot_w / slot_h plus knurl spacing — resize for travel-size tubes, paint tubes, etc.
Dimensions: 64 × 15 × 5 mm. Print time ~25 minutes at 0.2 mm.
