Description

PDF

I designed this build square for use in building foam board RC model aircraft. The inside corner is chamfered to allow checking for squareness while gluing to avoid gluing the square to the work piece.

Can be printed on the flange side without supports.

Material: PLA
Infill: 15%
Supports: No
