This is a remix of the Schrader car / truck valve caps to fit the common Presta bicycle tyre valves. (remix from https://www.thingiverse.com/thing:5471630) I defined the UNC #12-24 TPI threads and added these to the 'middle finger'.
The valve caps screw on to the common presta valve stems. I have printed in TPU to give a flexible cap. Someone tried printing in PLA and had a problem screwing on - whilst the TPU version was fine in TPU, with rigid materials use the PLA_finger_V2 which is rigid and threads on to presta
Have fun ... if a little cheeky!
