Intex Pool Adaptor for Rigid Shopvac hose

I've had the best results printing the model with the threaded section up rather than that as the base.  Any elephant footing distorts the threads.  

This is a remix to all the use of a 2.5" Rigid shopvac hose to connect to the Intex pool pump suction port which can then be used to vacuum the bottom of the pool. 

Changed the diameter of the port, and added a rim for the shop vac hose clip
