MTB/Bicycle bolt caps, fast print

A few caps you can put on the bolts of your bike to customize the look of your mountain bike or other bicycle. I printed mine using 0.2mm layer height, they take about a minute each to print. Print them as an upside-down mushroom (largest part on the build plate). You may have to play around with scaling. I printed a few dozen of them to get to these final measurements, but they may not fit your bolts perfectly. They work on my bike really well now.   I have been using them on my bike for over a year now, and only one out of 30 on my bike has fallen off.
