OneUp EDC Blind Plug

If you own a OneUp EDC multitool and have more than one bike you might want to share the EDC between those bikes. The problem is that one of your bikes now has a gaping hole in the steering tube. If you need both bikes for some reason or want to wash the bike without the EDC mounted you might want to plug said hole with something. 

I designed a simple blind plug that fits into the steerer tube in place of the EDC. All you need is an O-ring with an inner diameter of 18 mm and 2 mm thickness.
