This is a very simple model I made for the grandkids to have something to play with on Halloween.  I sized the holes to fit the glow stick bracelet connectors, so they fit tightly in the handle.  The glow stick then fits into the connector!  

This handle holds 3 glow sticks at a time for the kids to wave around in the dark!  Or light.  You know how kids are…

I printed this in PLA with 15% infill.  Shouldn't need supports but at 100mm high you might need a brim or some sort of bed adhesion depending on how your printer deals with taller stuff.
