Bench Cookie/Donut Hockey Puck Pyramids

cults3d

I really liked the design on this and was thinking around making my own! This was originally made for the 3d printable Bench Donut. However, I like the idea of using hockey pucks and found a video and some resources to create your own bench cookie things for pretty cheap using hockey pucks and some grip discs from Lee Valley. https://youtu.be/BLg32TCz5yc You don't have to weight them, and the rubber on the bottom is decently grippy even without adding anything. I rescaled the original up 108.6 percent to fit around a standard regulation hockey puck. This puts the OD of the base at 81.5mm and the pyramid at 50mm, and it clips very well over a puck. The increased scale makes using 3mm hardware more difficult - I honestly just filled the holes with E6000 glue and used 10mm long M3 allen head bolts as "pins". I'll note that the increased scale allows for the use of 1/4x20mm bolts through the middle if you want to go that route, rather than the original 6mm. The head socket perfectly fits a 7/16" hex head. This would allow for the addition of an inset t-nut into the puck to thread these in and out.
