As I already have remixed a straw holder which only fits the 150ml and 250ml bottles of WD-40 i was wondering if there is something universal….
…now stumbling across the printables.com "Flash Contests Theme: Last Meter" I went for the universal and minimal approach. I still had the 6mm diameter and 3mm high magnets lying around from another project….
….the design can be printed with 100mm (approx 4 inch) of filament. I also tested it with a 0.2mm nozzle and brought it down to 90mm, to be precise: 89,19317mm
