Designed this from scratch as none available 30mm hooks worked well for my daughter.
After some tweaks and reprints, this worked great for her crocheting with 4XL thread.
I printed in a smooth PET-G filament, but sure PLA will work as well.
Print with support. A bit of sanding with a 150grit sandpaper will ensure smooth operation, especially at the hook and where support was removed.
