Keychain Ruler
prusaprinters
This little guy comes in both metric and imperial versions and is a great way to finish out your spool! Much like Adam Savages arm tattoo this was mostly made with rough ideas in mind, estimating size and such (though is accurate enough for most use). For accurate measurements measure to the side of the cutout closest to the key ring as shown in dimension drawings. The metric one took 1.7m of 1.75mm filament and the imperial one took 2.19m of 1.75mm filament.LET COOL ALL THE WAY BEFORE TAKING OFF THE BED- It will warp and not be flat. SizingMetric:20mm wide and 100mm long (from the lip)Imperial:1 inch wide and 4 inches long (also from the lip)
