About this 3D model

NOTE: I HAVE STOPPED WORKING ON THIS FOR A LITTLE WHILE Thank you printrbot for publishing the drawings for the Jr. v2! disclaimer: I haven't [fully] tested it yet - UPDATES: ->V1.1 (4-19) -changed radii of various things -trimmed a bit off the body to save material and time, also for better clearance inside -rounded that a corner on the latch -added teeth on bottom of the inside when the extruder is held... for anticipated heat problems -packed it into one STL file So I've been playing with printrbot Jr v2 extruder parts for a while now... I wanted to challenge myself to make this extruder with the following features: -really easy latching, unlatching -3 pieces to print (minimum mechanical parts) -doesn't require any metal parts not already within the PBJrV2's extruder -could be printed without supports -fits in my printrbot (not yet made) - modular support for fans in various places and so I made this. the latching mechanism works similar to the original but puts less strain on the frame and is easier to undo for filament changes.
