This is a simple hook that magnetically attaches to any compatible surface. I designed it to hold my bed scraper on the side of my Centauri Carbon.

It uses 4 10mm diameter x 3mm thick magnets. Depending on your tolerance tuning, they may just snap in and hold well with a friction fit. If not just add a dab or adhesive like superglue or E6000.

I find them very useful for all sorts of things including build plate cleaning and scraping decals off of painted surfaces without scratching them.
