About this 3D model

Accelerator used, https://makerworld.com/en/models/93385#profileId-99949 I have designed a propeller adapter for a 3-bladed drone propeller, which can launch drone propellers, and can be used for both normal and reverse propellers. You only need to mirror print to get another one. I am K-Bao fpv, welcome to follow me on Douyin.
