Any Angle Clamp helper

I recently needed to glue together many pieces of wood at many different angles (usually obtuse angles). I found it difficult to find a proper clamping setup that was stable for most of these joints, so I made these.

These tools should allow you to apply clamping pressure perpendicular to almost any joint. My strategy was:
1. Use a machinist square to drop a perpendicular line to the edge(s) you intend to glue
2. Clamp the clamp-helper to your workpiece(s) so that the perpendicular line you found intersects the round portion of the clamp-helper. (This may mar soft wood, I'm sure you could use some sort of rubber or scrap wood as a buffer between the clamp-helper and your workpiece)
3. Clamp the joint using the round portion of the helper, thus applying force perpendicular to the mating surfaces.

It is absolutely still finicky, but when you find a good positioning of the clamp-helper, the joints are rock solid.

I printed these pretty beefy:
- PETG
- 50% infill
- 5 walls
