A script to generate snap-together holders for Sparkfun breakout-boards. The size is chosen specifically to agree with the Sparkfun polygonal proto-boards. This, however, isn't compatible with my previously published dodecahedral protoboard thing: the scale needed adjusting to accommodate all shapes of protoboard.I have tested and provided instances for 3 different sparkfun boards : the small 3.3v boost converter, the Arduino pro-mini, and the EasyDriver stepper motor driver. The standard Arduino required a holder too large for my build platform, but printing the holder in sections would work. Sometimes some trimming and adjustment was required as MakerBot did not build the part to exact specification.update : I added breakout_revised.scad. This file adds support for a default 2x2 piece with cutaways for connectors between the hinges. I think its a good candidate for a standard circuit board element. The revised script also significantly cleans up the code style. See radioshack.stl and isp.stl as example outputs of the revised script.compatible with http://www.thingiverse.com/thing:5859-1- Measure protoboard dimensions in millimeters -2- Use OpenScad script to generate custom holder -3- Print ( on Makerbot : calibrate oozebane, use comb, set width such that snaps are double-walled, but with little infill. ) -4- Clean -5- If necessary trim out slots for pins using a razor knife. -6- Assemble
