AC T-Nut Slider - 20mm Extrusion

Yup, it's a magnet on a stick, but it's an awesome combination for moving / holding those pesky T-nuts behind things with precision. This one is set up for 20 mm Extrusion channels, and uses a tiny 3mm x 3mm cylindrical rare earth magnet (easy find on eBay for under $1-2). Bendable plastic is a +, I use a PLA that has a bit of flex to it, but ABS or Nylon would likely be better. I did try more complicated handles, longer sticks, etc, they just get in the way. The K.I.S.S. mantra works very well
