Cup Holder
thingiverse
I wanted a magnetic cup holder for some little plastic cups I use for mixing epoxy. This is a friction-fit, customizable cup holder. I'm using both the pressure of the wall pressing inwards and the ridge of the cups catching on the individual layers of the print to hold the cups in place. The cups* do not* drop down to the bottom when you pull one out. The STL file I provided is set 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 so they'll need to be glued. If you want to use another size you'll have to use the customizer.
With this file you will be able to print Cup Holder with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Cup Holder.
