Motor shaft adapter 3mm to 5mm

I used this adapter for the RC Speed Tank by Bryant87. It is an adapter for 3.125mm to 5mm axles. To print it I recommend to start with default settings and increase/decrease flow depending on how well it fits (optimally it wouldn't have any noticeable play). There are three versions, but I recommend using the adapter_hole version, as I used it successfully.
Regarding the stability it seems to be very good, as my speed tank uses pretty strong motors and I never had a problem with these printed
