Shop Vac 2.5" M - M Connector

This connector is a Shop Vac 2.5" coupler to Shop Vac 2.5" connector.  The internal diameter (ID) is 2.28" and outer diameter (OD) is 2.6".  I done it as a layer height of 0.20 mm with a 0.40 mm nozzle.  If you have any feed back or need me to modify it or have any notes please let me know.  

Thanks for checking this out and I hope that it helps.
