[ Information ] A sister model of this “Split Ring” is available on the following page.   “Oval Carabiner (7 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

Post-Printing Tips

Even if the inner and outer rings are stuck together after printing, it may come off if you pinch it with both hands and wriggle it.

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.
