Ciao, this is a fan kit for use in RC models, but which can be used for other uses ... excellent if you want to make a small Overcraft :) The kit consists of various versions of impeller to be mounted on motor pins of common size. More details on the kit in the 1th video.

The performance obtained from the tests are visible in the images. More details about the test in the 2th video.

Suggest setting: The design is optimized for 0.4 nozzle. The impeller have bottom hole close by a 0.2 layer to facilitate the print. Print using the support and then break the single layer to free the hole.

• wall 0.8mm
• top/bottom 0.8mm
• infill 10% or 100% if you want redrill the hole for different motor pin

The impeller is made following a new concept I invented. More details about the concept in the 3th video.
