Hinge30

hinge20 remix. Original design: https://grabcad.com/library/hinge20-1 Changes over the previous design: * Designed for 30-series aluminum extrusion profiles * Increased allowable angle of rotation to 200 degrees (included angle) -> to hold position when rotated over center * End-to-channel mountable, but can be modified for either end-to-end, or channel-to-channel mounting configurations. * Experimented with rubber tubing as the center lynch pin (nothing special; saw it in a video, tried it out with what I had on hand, and worked great!) Inspired by David M and the openlab project. <3
