My daughter broke the handle ring on a Tretur blind roller from Ikea.
I could have printed the exact replacement but wanted a stronger one.
So I designed this one based on a solid 4mm shaft that goes through the existing clip, securing a more robust new handle.
EDIT 25 Feb 2019:
V2 version has smaller shaft pods outer diameter as it can be difficult to fit in place sometimes. Shaft pods are also 2mm longer as I had a too long shaft that I didn't want to cut.
