JB Vacuum Pump Coupling

I needed a Coupling for the motor to the pump on my JB DV-200N 7 CFM Vacuum Pump. You may have to scale this part a little depending how your printer prints. I printed it on my flashforge creator pro at 100% infill in ABS. Haven't run it a lot to make sure it will hold up but it should work until I get a new one ordered from JB.
