Mini CMS Detector

Do you love CERN's CMS Detector but want something a little easier to print? This model is for you! This simplified 3-part version can be printed in a bit more than 4 hours, and it's nearly as cool as the full model.

The endcaps can be glued in place, but a much better idea is to embed magnets in the prints so the endcaps can be opened. You'll need 4 magnets (I used 8mm x 3mm neodymium magnets), and you'll need to make negative space in the models to accommodate them. Make sure the holes line up between the different parts! I've included preconfigured 3mf files as examples.

You'll want to check carefully the orientation of the magnets so the endcaps stick to the barrel. What I do is stick the 4 magnets together to align the poles and then paint a dot on each one to mark their “north” poles. The magnets inserted in the endcaps and the first one of the barrel should have the dot facing up, and the second magnet of the barrel should have the dot facing down. If you print multiple models, make sure you align the magnets between them if you want to mix and match endcaps. I also recommend a couple of drops of superglue before you drop the magnet in, it will keep it from rattling around or coming out before the next layer is printed.

Combined all barrel components into a single piece, made significant modifications to make it faster and easier to print and rescaled it to 35%.
