Something I made as a simple way of testing components and getting power to lashed together test circuits. My own model from scratch, but heavily influenced by http://www.thingiverse.com/thing:168522 Uses 0.6mm patch wire and a cheap slide switch from ebay (http://www.ebay.co.uk/itm/351353359962?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) Printed in PLA, 0.1mm layers at 50mm/s Can be a pig to wire if the holes close up - i heated some wire with a soldering iron and pushed it through to open the holes. Hopefully the photos show the wiring clear enough. Some needle nose pliers help a lot pulling the wires through and bending them.
