Flash insulated air mattress drying adapter

thingiverse

This adapter connects an REI Flash backpacking insulated air mattress's inflation port to a small squirrel-cage blower, speeding up drying inside the sleeping pad. Inflating the Flash on the trail with your mouth/lungs blows very moist air into it. Once home, drying out the inside is difficult. REI advises laying the mattress flat and opening both ports until it dries, but I find I can still see moisture droplets inside for many days this way. Shine a flashlight from the backside to spot these droplets. Using this adapter connected to the inflation port and leaving the deflation port open allows me to dry a mattress out overnight. The blower used generates very low pressure, so it won't damage pad seams by overinflation. (The pad does not fully inflate while being dried.) The 2017 Flash has a different design (squarer) and color (red), but should still fit since it's listed as using the same pump accessories. I needed this fan: http://www.amazon.com/gp/product/B00MJU6JR2 My version of the Flash looks like this: http://www.backpackgeartest.org/reviews/Sleep%20Gear/Pads%20and%20Air%20Mattresses/REI%20Flash%20Insulated%20Air%20Sleeping%20Pad/Test%20Report%20by%20Brian%20Hartman/ This fan has a small ridge on top, and my adapter design latches onto this ridge to stay put. It also latches into the pad's inflation port. I power the fan with a small 12v supply. In use, the blower draws less than 100mA. I printed this successfully using PLA, 0.2mm layers, 0.4mm nozzle size, and it has a good snap fit on both the pad port and the fan.
