Hair dryer nozzle adapter for air mattress

I have this blow up mattress that needs to be inflated every so often when I have guests over... thing is, I don't have a very good air pump to accompany it. But, I DO have a nice hair dryer with a 'cold' setting (H&D model number HD-1205). Its nozzle opening is 25mmx50mm whereas the blow up mattress opening is round... SO, I made this adapter. Works beautifully and I can skimp out on buying a real air pump. Yay!

Now, that's what I call living the 3D print lifestyle.... aww-yeah!
