Let 3D printing enable and empower your young Gretzky! The perfect 'thing" for a young hockey player.
This is a roller hockey puck with replaceable, snap-in "runners". Just print more runners when the original runners get worn down.
My son asked if it would be possible to print a hockey puck and I didn't want to waste the plastic on an average solid puck. I told him that we could design a puck specifically for roller hockey that would allow the puck to glide across the surface on runners. We drew it up in Rhino and printed the puck and runners in PLA on our Prusa V2.
Print the puck and then print 12 runners. The puck holes may need to be reamed with a drill bit. I left them undersized in the model to allow a snug fit for the runners. Insert six runners into the holes located on each side of the puck. I used a rubber mallet to insure that they were seated in the recesses of the printed puck. I printed the runners in PLA and they allow for a slick surface to glide across concrete. Print replacement runners when the old ones get worn or print more pucks and let your child shoot at the garage door all day long.
I included 6 runners into one file for printing, but have also uploaded the a file with a single runner.
