When I ride my ADVenture bike I often stop and take the tyres down a bit.. airdown.. so I am always looking around for some little stick which is the perfect size to push the inside of the valve.. so, I made this up! .. keep it in your pocket.. print up a few, give to you mates - very handy.

fine

Pretty easy print - might want to try something other than PLA+ if it is going to get very hot to be left in the sun - mine stays in my pocket so no issue there.

just knocked it up using Fusio360-->STL-->into Cura.. slice up..->gCODE.. then onto printer
