Cup Holder

thingiverse

I needed a magnetic cup holder for some tiny plastic cups I use to mix epoxy. This is a friction-fit, customizable cup holder that works beautifully. I'm using both the pressure of the wall pushing inwards and the ridge of the cups catching on each individual layer of the print to hold the cups securely in place. The cups do not fall down to the bottom when you pull one out. The STL file I provided is designed for 12mm by 3mm magnets. The 3mm magnets will be slightly recessed so as not to scratch the magnetic surface and they are a loose fit, requiring glue to hold them in place. If you want to use another size, you'll need to use the customizer.
