Wide mouth mason threaded jar lid (86mm)

thingiverse

I grabbed the lid from thing:478811, took it apart, and discovered that to get a snug fit, I needed to shrink its diameter down to 94.8mm (originally 96mm). Using Cura's Scaling tool made sure everything shrunk uniformly, including the Z-axis. Next, I opened Autodesk123D, where I added a plate, a ring, and some ribs directly into the lid's design - I prefer bumps over indents every time. A size label was also added since I print many lids. The result was a nice tight fit. However, I haven't yet tested whether it can be flipped upside down without issues. I made sure to keep the original designer's licensing intact and clearly stated that I make no claims to this design as my own creation. Print Settings: Printer: Kossel Rafts: No Supports: No Resolution: 0.2mm Infill: 30% Notes: I used .2mm and higher resolutions work too, provided you stay under 80% of your nozzle diameter.
