I actually bought Ryobi Workshop Blower just to use it on air mattresses that my kids use when they go camping, for their swimming toys and for my intlatable paintball bunkers.

The blower is RYOBI ONE+ R18TB-0, and it's about 60 euros here in Europe. The blower has very good air flow but to get most use out of it, you really need some adaptors for it. This adaptor fits our camping mattresses and I'm sure all paintball bunkers available commercially. I have not yet tried it on swimming toys, since my kids forgot all of them to a cabin they were visiting last week. I think the outer diameter (of the smaller tube) was 17.5 mm. I left the part downstairs and it's too hot to go back there (thanks climate change, this should be Finland and not Sahara).

The best part of this adaptor is, that it actually fits the blower totally perfectly, unlike the hose part that came with it, which is very hard to put on and off.

This simple print totally justifies the purchase of 3D printer AND Ryobi blower. If you have ever pumped one of those camping mattresses, you would be agreeing with me!

It takes 9.6 meters of filament when prited with skirt.
Printing time is under 3 hours with print speed of 60 mm/s.

Trust me, you'll be blown away once you've used this! Did you get it? Blown away...I need to get a stand up gig!
