1/2" Bolt Thumb Screw, embedded Magnet

These are thumb-screw caps for 1/2" bolts (3/4" or 19mm head) that have an embedded magnet to hold them onto the bolt.

My use is for levelling feet on our folding camp table - which doesn't have enough room to store the feet when it's folded-up, so I wanted something removeable. Magnets work perfectly for this.

There are two versions - a 10mm x 2.5mm magnet which you can get on Amazon or Ali Express and a larger 12.75mm x 3.5mm magnet I get from Lee Valley. The Lee Valley magnets are much better, but a bit more expensive.

Set your slicer to pause while you insert the magnet and then continue printing.
