Where to buy the plastic hex hubs

[AndersM]

The plastic hex hubs that fits customs wheels were can i buy those? There are not part of the parts list in the manual.
The Savage XS uses 1.65x10 mm pins most uses 2mm

Also I need the same offset because changing battery is hard as it is with my custom Louise MT Rock wheels

Sadly I'm in Europe. 🙁

Wont the screw add imbalance, and if you skip the screw it might not sit tight around the axle / wheel hub?
