Dryer attachment for inflatables

This is an attachment made for the airpump for my inflatable spa.. The idea is to use the airpump to dry out the interior of the inflatable.. The attachment fit into the air-hole on the spa and you can direct the flow of air so that it will circulate through the inflatable, picking up moisture and leave the inflatable… 

It will take some time to expell all of the moisture inside…
