Split Ring (6 sizes)

2 shapes and 6 sizes each.

A removable ring that is harder to use than carabiners. But I wanted something sturdier with a simple shape, so I designed this.

2 types of data are available for each ring.

[Easy-to-Print] ─ Larger tolerance. The end of the ring-line comes off easily.
[Hard-to-Print] ─ Smaller tolerance. The end of the ring-line can be held in place.

Print Instructions

If the printed ring sticks together and does not open, try scaling up an Easy-to-Print model in a slicer app. (e.g. 120% or more)
This will increase the clearance between the inner and outer rings and make it even easier to print.

Brims/Rafts ─ Doesn't Matter
Supports ─ No

How to Use

Open ─
This split ring does not open horizontally. To open it, shift the end of the outer ring-line vertically.

Close ─
There are notches on both ends of the ring-line to hold them in place. Therefore, the inner end needs to be fitted first to close the ring. The outer end should be fitted last.
