M5 Captive-Nut Mini C-Clamp
A small C-clamp frame for glue-ups and holding small parts. It opens to 46 mm with a 34 mm throat and is 60 x 80 x 14 mm overall. Drop a standard M5 hex nut (8 mm across flats) into the slot in the top arm and drive any M5 bolt through it; add a nut or knob on the bolt head to turn it. The frame prints flat, so the clamping force runs along the layers instead of pulling them apart.
Picture Frame Band Clamp Corner Block
This corner block is for strap or band clamps when you glue up mitred picture frames and boxes. Print four. Each block has a pair of 90° jaws, 40 mm long and 21 mm tall, that hold the frame square. A rounded R12 outer face lets the strap wrap without kinking, and a 3 mm bottom lip keeps a strap of any width from sliding off. A 3 mm leveling ledge holds all four corners in one plane, and a 6 mm through-hole at the inside corner lets glue squeeze-out drip away so the joint doesn't glue itself to the block.
Cambered Truss Glue-Up Clamping Caul
A 160 x 30 x 18 mm Warren-truss clamping caul for edge-gluing panels and laminating. Its contact edge is curved with a 1.5 mm camber, so a single clamp at each end presses the middle of the joint first and spreads even pressure along the whole length. It prints flat with the clamping load in the layer plane, has jaw seats at both ends so F-clamps and quick-grip clamps don't slide off, and a 6 mm hanging hole. Print two and use them as a pair.
Right Angle Corner Clamp Jig
An 80 mm L-block that holds two boards at a true 90° while glue sets, with open windows so a spring clamp reaches straight through to the workpiece and a rounded corner relief for squeeze-out. Two 4.5 mm holes let you screw it down to a bench or assembly board.
