Impr3za Casadio Upgraded Wheel Hub M2x4 Heat-Set

This upgraded wheel hub was designed to fix a common issue — stripped bolt holes caused by overtightening or frequent use. The new version replaces the original plastic threads with durable M2x4 brass heat-set inserts, greatly improving the strength and longevity of the connection.
Perfect for any small mechanical or robotic project where repeated assembly is required.
Printed in PETG for strength, but compatible with PLA or ABS as well.

Features:

• Uses M2x4 brass heat-set inserts
• Reinforced design for higher durability
• Reusable and serviceable connection
• Compatible with most 3D-printed wheel mounts
