Someone in the comments asked for a smaller prop. I was intrigued and learned a few new tools to help me remix this. Thanks to Koycns for a great model and providing the extra files to make it easy.
Hey this Design is really awesome, very great fun we have :-) :-) :-) Great Job you've made. Without grease just printed, mounted and launched the propellers my grand-son have a lot of fun with it. Thank You.
