Drysuit dryer: reducer for B-Air VP-20

thingiverse

When on the move, drying out your dry suit can be a real challenge without that bulky PVC rack. I designed a custom reducing manifold to fit perfectly on the face of a B-Air VP-20 air mover. These powerful air movers are easily found at Home Depot and similar stores for about $90 CAD. The reducer is specifically made to match the Rigid 1"7/8 x 7' vacuum extensions sold at HD, which cost around $24 each. Since you'll need four of these hoses, it can add up quickly, but using an old home vacuum hose as a cheaper alternative might be worth considering. This blower produces impressive pressure and airflow, even with low power settings, making quick work of drying out your dry suit. These units use induction motors, eliminating the risk of ozone generation. I printed this custom part at 5% infill and found it to be sufficient for everyday use, but not robust enough for heavy handling. Printing with ABS material at 20% infill would likely provide a more durable finish. This design is specifically tailored to fit diagonally on a Prusa i3 mk2 printer bed. When assembling the part, remember to pre-drill holes along the long edges before screwing them together, as overtightening can cause cracking.
