Being annoyed that coats tended to slide off our coat rack, especially with more than one garment on each hook, I decided to print an extension to elongate the hooks. The coat rack is an older model from IKEA.

This one is printed in Das Filament PETG Beige. Print and design files included.

There's also a shorter version to test for snugness, which can also be used as a cap (instead of full length).
