Corner bracket for polygonal frame

thingiverse

a parameterized corner and side bracket for constructing polygons. by default, it makes hexagons the idea is that you use square rod of uniform length to construct a frame, into which you stretch a piece of fabric or something. i used square wooden dowel rods. the corners have holes for lashing string and for hanging. in principle, this file is whatever dimension you want. i envisioned it being metric, in mm. features of OpenSCAD this model prominently uses: - minkowski summing for rounding - difference, for cutting - for loops, for placing the screw holes known issues: - the corner tabs are NOT correctly placed. they are approximately correct, but as you change the angle, you get some error. was pretty much correct for 6 sides (hexagon). - stupid things happen if the roundednesses are too high. namely, for the tabs, a roundedness that's too high will result in no tabs at all. --- magic constants: - no known magic constants at this time. amazing.
