This is a working Wrench ratchet tool, this is the first thing i made on my new Duplicator 4. All models drawn in Solidworks. Extra: Socket Wrench pipe: http://www.thingiverse.com/thing:219190 http://youtu.be/HacHFjdPr9A Everything is made inn ABS, also compression spring Parts are glued together with ABS soup. The compression of the spring is quite good. Raft is only used for the smallest parts like spring and pin. Use ABS soup to make parts stick to glass plate, this works very well. I`m new so i use Makerware for now, have tried ReplicatorG but for me is Makerware fastest and easiest. Included orginal base house.stl but this part needs support for printing To modify print setting in Makerware i recommend PROFTWEAK from Nothinglabs (http://nothinglabs.blogspot.no/2013/09/introducing-proftweak-makerware-profile.html)
