Office Chair Caster Stem Spacer

This is a small cylindrical spacer designed for office chair caster wheels that require an insert for proper fit. The part has an 11 mm inner diameter and a 22 mm overall length, making it suitable for chairs where the caster stem needs additional spacing or stabilization. It installs by sliding into place and helps ensure the wheel seats correctly and stays secure. Simple, lightweight print intended for quick replacement of a missing or worn spacer. Yes I have tested these and they work great, it is a simple part but needs to be properly fitted to your chair. 

Printing in PLA works “well enough” , but PETG or ABS is recommended for higher durability (it is what I used).
