Angle brace for RC airplane

thingiverse

This is a 90-degree angle brace for "foamie" RC airplanes constructed with square foamboard tubes. Specifically, I created this piece for an Experimental Airlines Axon to keep the fuselage tubes square and prevent racking. The braces weigh approximately 1.2 grams each (PETG), and installation is straightforward using hot glue. A pair of braces can be fitted side-by-side in a nominal 68-70 mm external square tube made from Dollar Tree foam board. They also function as mini-bulkheads for mounting small components, featuring three small holes for routing wires, pushrods, etc. Print Settings Printer: Monoprice Maker Select Rafts: No Supports: No Resolution: 0.25 mm Infill: 100% Notes: I printed mine in PETG for extra resiliency, but ABS or PLA should work. In Simplify3D, I set for 30% rectilinear infill with 2 perimeters and 2 (each) solid top and bottom layers, which essentially makes it a 100% infilled part weighing approximately 1.2 grams. Post-Printing Remove the part from the print bed, trim off any excess material, and install wherever 90-degree bracing is needed using your preferred adhesive.
