These are a modification of Mike Smith's triangles. I am calling them "Builder's Squares". They are 3" on the long side and 1/75" on the short side and, of course, the sides are at a 90-degree angle. Use these to block up your frames (or wherever you need a straight edge, etc.) They have holes on four sides for pinning to your building board.
These are sold in packs of four.
Printed in ABS. Prototype shown in photos. Minor color changes possible for Production items.
