Gecko Magnet

thingiverse

I added magnets to ModernGnome's fantastic little "Gecko DeskPal" model. The holes fit 10x2mm magnets perfectly. I used neodymium magnets from Amazon, getting 120 for around $10 (or about $6 on Aliexpress if you're willing to wait). One magnet is enough, but I used two to hold heavier items on my fridge. You don't need any supports; a dab of superglue will secure the magnets in place. If the holes are too tight, just scrape the edges with a scalpel or knife, or push the magnets in using a hot soldering iron. I recommend glue no matter how tight, as the magnets are incredibly strong and will come out eventually.
