This version is about half the width of the original (50 mm), which means its 1/8 the volume and a much faster print (yay math!). i find it takes me ~2 hours to print one (and ~8 for the original)
Rather than just being a straight scaling, this version has been tweaked so taht it will still rotate. The main differences are the number of gear teeth (much fewer, and larger), gear ratio (it now takes 2 rotations to realign, unfortunately) and pins (made much beefier, and they are all one length).
Additionally, there is a hole through the tip so that it can serve as a keychain! Print them out by the dozen and give them to friends/family/cute girls on the bus!
