Description
A small size blower made for the purpose of inflating an inflatable bed. Didn't want to bring along a big and heavy blower for my camping trips. This one uses a small dc motor powered by a 5v USB. The one shown in my video is using 10k rpm but it works much better with a 20k rpm motor or higher. The impeller was designed to fit on an 11 teeth gear. I use plastic gear because the motor shaft will be too hot for PLA to withstand. How firm the bed can be inflated depends very much on the power of the dc motor but for this application, it's just enough for my little kids' weight.
Non-printed parts required:
DC Motor for reference: https://s.click.aliexpress.com/e/_9GPcvq
Plastic Gears: https://s.click.aliexpress.com/e/_9RpH1i
2x M4 8mm screws/nuts
The adapter is optional but should be printed in TPU. This is what connects the blower to the inlet of the inflatable bed.
