Wall mounted double pendulum

thingiverse

This is a Double Pendulum attached to your Wall. Prepare: What you need are 4 2" Deck Screws, and 4-5 Ball Bearings which can be purchased here https://amzn.to/3c0mZnv for $7. Print the Long Pendulum with 60-100% Infill at .2mm Resolution. Print the Pendulum Separator with 100% Infill at .2mm Resolution and Supports. Print the Screw with 100% Infill at .2-.12mm Resolution and Rafts (breaks somewhat easily). Print the Short Pendulum with 50-100% Infill at .2mm Resolution. Print the Wall Mount with 100% Infill at .2mm Resolution. Assembly: Take the longer pendulum, and 2 Ball Bearings, and insert the bearings into the pendulum. You'll probably need to use a tiny amount of glue to get them to stick; hot glue is available if needed. Then do the same thing for the smaller pendulum. Sand down the Pendulum Separator in order for it to fit into the bearing's. Drill 4 holes into the Wall Mount base that are at about the 12, 3, 6, 9 positions. Find a stud in the wall and make sure you have enough space (the radius of the Double Pendulum is 58cm or a bit less than 2 feet). Then attach the Wall Mount to the wall using the 4 Deck Screws. Attach the long bar to the Wall Mount screw, but only tighten it a bit more than finger tight (the screw can break if you tighten it too much). Notes: The pendulum will hit your wall if it spins too fast. The Screw will break eventually. Have fun.
