Tired of your funnels rolling around? I was. I decided to make these little funnel holders that utilize 6pc of a 12x3mm magnet on the back. I have 3 sizes, small, medium, and large. Dimensions for each are below. These holders, with magnets, will stick to the side of your toolbox and allow you to stack some funnels into them when not in use.

Base size (area with magnet holes): 101mm (tall) x 40mm (wide) x 6mm (thick). Same for all sizes (S, M, L)

Small (S): Circle size @ 50x50mm. Circle is 32mm from magnetic base.

Medium (M): Circle size @ 62.5x62.5mm. Circle is 56mm from magnetic base.

Large (L): Circle size @ 75x75mm. Circle is 65mm from magnetic base.

Actual photos of the part above, show the "Small (S)" size.

Print Settings/Instructions: Use your own settings. No supports are needed as long as the funnel circle is printed touching the build plate and the magnetic base is upright as shown in the STL files. My printer (K1 Max) has no problems with the magnet circles with the base upright. Magnets on back are press fit. Best way to do it is to use a small hammer and tap the magnet into place.

This is a work in progress, and I have not printed the M and L sizes yet, but they should work fine as long as the funnels are not too heavy and thick. If the funnel is too heavy and thick, I would assume the magnet strength would be the weakest link as opposed to the print itself.
