I have these cellular window shades in my house and the handles have bugged me for ages. They were obviously designed to fit around the bottom of the shade, but they're clearly too small to actually fit. So, they only sort-of fit and I have to be careful not to pull them off when lifting the shade up and down.

It finally dawned on me I could make better replacements that actually fit. I stayed fairly close to the basic design and made a few tweaks to get a good fit. When printed in PLA they're flexible enough to snap around the profile, but rigid and tight enough to not come off easily.

My shades have a JC Penny label on them, but I suspect this may be a relatively standard model sold under different brand names.

Since this has a somewhat “long and skinny” profile on the print bed, you may or may not have some shrinking/lifting issues. If so, you may want to add a brim.
