Plum Bob Spool

thingiverse

I designed this to fit a Swanson hexagonal plum bob. The inside edge of the opening has a small lip, so when the plum bob goes in, it goes in snug. Once it's past the lip though, it's looser (though it doesn't rattle) and is easy to pull back out. The end of this bob has a metal ring used for hanging the plum bob. The end of this spool has a couple of pegs for that ring to attach to, to keep the spool from unspooling. The magnet channel can hold five small magnets. It was designed for these: https://amzn.to/2qaC9S3 The magnet dimensions are: 2mm tall with 6mm in diameter Even the strongest magnet of that size won't allow the plum bob to just hang from the spool when it's attached to something magnetically, because the bob itself is quite heavy. The magnets have other uses, but you don't *have* to add them. Timelapse: https://youtu.be/ICP228KTF9k This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/gJQLcX0AxEs
