Holder for handlebars to keep them straight while on a stand, 

It keeps the handlebar from rolling over and hitting the frame.

Printed in 2 pieces to keep small enough for most printers.  There are 2 nuts and bolts required.  The hex cutouts are designed for 1/2-20 hardware but should also work for 5 or 6mm as well. 

recommended to print flat using "tree" supports
