Any Angle Clamp helper

thingiverse

I recently needed to glue together many pieces of wood at various angles, often obtuse angles. It was challenging to find a suitable clamping setup that remained stable for most of these joints, so I created these tools. These devices allow you to apply clamping pressure perpendicular to almost any joint. My plan involved the following steps: 1. Use a machinist square to drop a perpendicular line on the edge(s) intended for gluing. 2. Clamp the clamp-helper to your workpiece(s) so that the perpendicular line intersects the round portion of the clamp-helper. (This may scratch soft wood; using a rubber or scrap wood buffer between the clamp-helper and workpiece is recommended.) 3. Clamp the joint using the round portion of the helper, thus applying force perpendicular to the mating surfaces. The setup remains somewhat finicky, but when you find an optimal positioning of the clamp-helper, the joints become rock solid. I printed these sturdy parts: - PETG - 50% infill - 5 walls - 5 bottom/top layers - 0.4mm layer height (this reduced the print time for the smaller clamp-helper to just under three hours) After printing about 20 joints with these tools, they never showed any signs of weakness, no matter how hard I tried to apply pressure. Large measures approximately six inches end to end, while small measures roughly four inches. The picture shows a solid-fill end for the large model; both models have a hollow end, as it was discovered that this did not impact strength and removing it decreased printing time.
