Magnetic Lint Roller v2

I work as a welder, and I use a version of this to get steel slivers and shavings off my skin and clothes. You can use any material except TPU. I'd recommend at least a 20% infill, but no more than 50% infill. It's a super simple design, you'll need a wire brush to get all the steel slivers and shavings off. The bar magnet slots will be very tight fitting, you might need to shave them open a little more, though I doubt it.

You'll also need:

• Super glue
• 0.5" diameter wooden dowel rod
  You can buy this at Walmart in the crafts section.
• 8 Bar magnets
