UPVC Window / Door Block Riser Guide Clip

I’ve designed a PVC window guide block clip thingy… not sure on the correct term, as mine were brittle.
Took the measurements from an existing clip using callipers and sketched it up in Shapr3D.

I can’t say what window frames this fits, I’m not sure if this is a universal thing or not so I’ve added an image of basic dimensions as my windows are at least 30 years old so maybe the designs and shapes have changed since.

I printed in white Hyper PLA as here in the UK it doesn’t really get hot enough for PLA to warp. If you live in hotter places or have a window in direct sunlight or even black PVC then I’d suggest a material that copes with heat better.

Thank you!
