I absolutly love my multi drive and 2 stubsters, but I would like to get the stubsters some bkade mounts and 4mm adapters all of their own. It seems they’re the only parts that are not available in the store.
Hey, this is definitely in the works! You can expect to see these available on the store in the near future 
SO Happy to hear it!!! Got my stubster not long ago and I love it, but it doesn’t have a blade or 4mm adapter mount - so I still keep the Multi drive and stubster together to share bits.
