Pro-Line 6x30 12mm Hex Adapter for Robak | ProLine

The HSP 108015 axle shaft has a thread that is too short to use it with the original adapter. 
I reduced the thickness of the hub from 4 to 2.2mm. See drawing.

That blind hole is there on purpose. Helps generating supports better. Remove it along with the supports.

to be used with:

• Pro-Line 6x30 Removable Hex Wheels (e.g. Badlands MX28 2.8")
• HSP 108015 Axle Shaft (or similar)
• HSP 122042 Wheel Hex (or similar)
• M4 Washer DIN 125; ISO 7089
