Shape Rollerz Version 2 - After several comments I went to a uniform eye design, the square and triangle eyes were criticized and a little freaking. Also the hand hole on the triangle roller dropped past the wheels which would create a pinching hazard. So these are the updated design. Models coming next.
Triangle Rollerz V1 - CAD verison, model coming soon
Circle Rollerz V1
Rectangle Rollerz V1
Tri-Roller Model V2 - I printed a ObJet model just to check scale and sizing. Looks pretty good.
