O-Ring Sizing Cones
thingiverse
These cones make measuring the inner diameter of O-rings very easy and reliable for nonprofessional use. They're made for DIN3771 standard sizes. A Vernier caliper is needed to check the step diameter. I use the following sizing chart as a reference. http://www.prepol.com/PPE-Uploads/Oring_sizes_DIN3771.pdf Print Settings Rafts: No Supports: No Resolution: 0.1 - 0.25 mm layer height Infill: 30% Notes: Test printed with ABS, 0.25mm layer height, 30% infill
