Turn an 8mm threaded shaft into a secure 4-screw wheel mount with this compact adapter. It screws onto an M8 threaded axle/shaft and provides a four-hole mounting pattern for wheels that use screw fastening. I used ikea caster wheels , all ikea wheels use this thread.

Great for DIY carts, robotics projects, small electric vehicles, workshop builds, and custom wheel conversions. The four-screw design spreads the load more evenly than a single center fastener and makes wheel installation/removal simple.

Features:

• Converts an 8mm threaded shaft to a 4-screw wheel mount
• Secure, practical wheel attachment
• Compact and easy to print
• Ideal for custom mechanical and robotics projects
• Designed for wheels with a compatible 4-hole screw pattern

Print recommendations:
Print in PETG, ABS, ASA, nylon, or another strong material. Use high wall count and solid infill for best strength. Avoid PLA for heavy loads, high temperatures, or powered applications.

Important:
Check the thread pitch, wheel hole spacing, screw size, and axle alignment before use. For high-speed or load-bearing projects, test carefully and use suitable screws, washers, and thread locking where needed.
