Twisty Pug Wing Spring

thingiverse

This is designed to stop the wings falling off of the Angelwings Designs Twisty Pug RC glider. My servo linkages aren't great and i don't trust them to keep the wings attached to the fuselage anymore. Printed in TPU to act as a spring, but PLA might also work. It should attached above the carbon spar with a piece of tape at each end, ideally Blenderm tape. Mark where the ends come to without any stretch, then tape it down with 1-2mm of stretch in it. Too much stretch and you won't get accurate servo centering, but 2 different centre positions. Don't stretch it if it's made from PLA, use paper as a temporary shim to make sure there's a gap between each wing and the fuselage sides. 0.4mm nozzle, 0.1mm layer height, (0.12mm for Ender 3) 100% concentric infill, first layer pattern: concentric, Align the flat face to the build plate, trim blobs off after with flush cutters.
