Sphero Ultimate Ramp Kit for the #MAKE5000 Challenge

This is a set of ramps designed for Sphero during the #Make5000 contest.
For the press fit parts, the first version of this set has an offset of 0.1mm radius (0.2mm diameter).
This works for some printers but you may want a different offset. Let me know how much of an offset your printer needs for round snap/press fit parts and I'll upload a new version!
Most of the ramps are designed with a gentle slope for Sphero, this means they need to be placed directly on the floor. S2,S3,S4 are designed with stacking in mind.
Enjoy!
