About this 3D model

The end plugs fell out of the handle bars on my mountain bike. I am using my bike for a triathlon this weekend and the race officials want all holes plugged so that the holes are not an additional hazard if there is a crash during the race. I took an existing SCAD file (http://www.thingiverse.com/thing:13301) and modified it as the basis of this plug. I printed 3/4" diameter plugs, but the SCAD file is parametric so you should be able to make any diameter plug.
