Inner tube sealant funnel

By Phil

A simple funnel for adding sealant to inner tubes with removable cores.I have been unlucky enough to get a lot of flat tyres recently so I've been looking for a solution. My mountain bike uses tubeless tyres with Stans NOTUBES sealant, I decided to try putting some in my road tubes. Instead of buying a syringe to do so I made this.The tip of the funnel sits inside the valve (with the core removed) and allows you to pour the sealant in.Print upside-down.
