boulder2009's fan

Improve and fixed version of boulder2009's fan. I add a pair of handle, and replace the metal screw, with 3d printed nails, which makes the model now 100% 3D printed. Rest of the issuses are all handled. I'll delet this if it infringes. Rivet Installation Method: After placing it in position, briefly heat it with an electric soldering iron or a lighter. Initially, apply heat for as short a time as possible, such as only 0.5 seconds, to soften it. Then, use pliers or press it against a flat surface to deform and flatten it until its width exceeds the hole diameter. Reference:精雕细琢的小手摇扇 - 免费 3D 打印模型 - MakerWorld
