OpenSCAD library: simple pin and block snap connector

thingiverse

OpenSCAD library for effortless joining and separating parts, easy-to-print. After conducting experiments with "mushroom" shaped cylindrical connections, which suffered from weaker pins due to printing upright, I settled on this flat design instead. Due to their preferred printing direction, these should be suitable for connecting bars, beams, and plates oriented perpendicularly to each other. They don't lock into place but rather provide a secure hold, requiring an extraction force comparable to the insertion force. Modifying the bulge shape would change that dynamic, but for their intended purpose, a symmetrical force response is precisely what I needed. Custom Section Versions: v0.0.1 2016-10-10, ls: Initial version v0.0.2 2016-10-10, ls: Changing the slot to a wedge should increase stability. v0.0.3 2016-10-11, ls: Wall parameter now accurately reflects real wall strength; I neglected to account for slack in earlier versions. v0.0.4 2016-10-11, ls: Made object height a separate configuration item and updated demo placement.
