I stumbled upon a glowstick holder for 25mm straps here on thingiverse, printed it, but my glowsticks didn't hold.
So i made my own. I listed the original as remix-source. Please check it out, it might suit your needs better, depending on the size of your glowsticks.
This one has an inner diameter of 4.5mm.
I added a triple glowstickholder, because i thought it would be a nice idea for a "Backpack-Backlight". I rarely walk in the dark, but if i do it would be nice to have some sort of saftey-light, which doesn't need batteries.
I have not yet printed it...it might need a raft / brim.
This Version is pretty compact..
Doesn't Matter - Not much Infill anyway
If you have Adhesion-Problems, print with Raft or Brim as you like.
