You can find several of my original designs on my Thingiverse page here and on the Q Pack GitHub located HERE. One worth checking out is the Ghostbusters Proton Wand pop-mech with twist. Downloadable parts and instructions allow for it to be built entirely 3d printed, or with an internal PVC support tube, or using screen accurate aluminum tubes.
