Originally this idea was meant to fit into the "Ergonomic Workshop Aids" contest, sadly I don't think this idea will fit into the spirit of the contest. Nonetheless, I will attempt to make a system that can quickly accommodate a variety of friction caps. I'm simply trying to outline my idea here.
Idea Name: HandyCaps (BetterCaps)
Simple Vision: Essentially better caps and a system to open/close the caps.
Precise Vision: Parametric modeling of better caps to replace the included caps on gluesticks, chapsticks, expo markers, other friction fit caps, etc.
Future Project Additions:
The author marked this model as their own original creation.
