A replacement glider for a curtain track/rail.

I do not know which curtain this originally belongs to, I modeled the replacement part after a broken one, as seen in the picture (original is the one on the left).

The hook ring has a slightly different form, it is more of an ellipsis in the replacement, whereas the original has straight sides on the inside. Though, rail dimensions should match exactly.

Dimensions are the following (in mm):

Although the OpenSCAD files are included, so if you understand my terrible variable naming (programmer issue :D), you can customize it. Requires BOSL2.

Print lying on the side for strength, with supports (zig-zag support worked best for me).
