Day 147 - Fidget Cube with Smaller Hinges

After more testing we figured out how small we can make the hinges on the Fidget Cube and still have it print reliably in one piece. (The answer: 1.5mm radius.)

STL file: http://www.geekhaus.com/makerhome/day147_fidgetcube_black.stl
Thingiverse link: http://www.thingiverse.com/thing:230139

Settings: MakerWare .2mm/standard in about 90 minutes, with no raft and no supports, one one piece. In the Customizer settings below, 1.5mm is the smallest that I could make hinge_radius before things got unreliable. However, hinge_clearance could safely be reduced if a stiffer model was desired.
snub = yes
cube_height = 20
stacking_clearance = .3
hinge_radius = 1.5
hinge_clearance = .5
Fun fact: The picture below shows what it means to "design to fail". To make the Customizable Print-In-Place Fidget Cube we went through a lot of iterations of testing, re-testing, and failure.

UPDATE: The Print-In-Place Fidget Cube was Featured on Thingiverse today! Thank you, Thingiverse!
