Desk Fan

Thank you all for boosting the 9cm fan! I've also received too many private messages asking for 12cm and 14cm versions, but I've been busy and only recently found time

Although summer is over, life is full of surprises, which makes it interesting

So let's launch an off-season new product

Previously, I didn't plan to make a 12cm version because I felt it would be too large, which turned out to be true. Printing just the main frame takes 5 hours, and the whole thing takes a full day. The materials and adjustments for testing required sleeping and fixing them the next day... Everyone should be mentally prepared

This version also supports 14cm fans, but the size is quite extreme, also to allow A1 mini users to print it, which unexpectedly achieved a very OCD-satisfying effect. Please pay attention to the installation method for the 14cm fan below. I have very few 14cm fans on hand, so I'll leave it to everyone to test

Overall, screws are avoided (or minimized) as much as possible, and the screws are completely hidden on the front

Therefore, the front panel is pressed directly into place. The fan screws have also been moved to the back, and two screws are sufficient. I also strongly recommend using reverse blade fans; the visual effect is completely different

At the same time, because of the larger volume, a handle was added, and the knob was changed to one that is easier to operate with one hand (finger)

The previous 9cm cover often fell off easily, so this time a buckle was added. It takes a bit of effort to remove, but a groove was made to make it easier to apply force

The front cover part will definitely have DLC later, but I'm not sure what the specific demands are, so private messages are welcome

This version still has a few unused screw holes for the feet, which will be for the power bank DLC later. Because of its larger volume, it actually feels like it could fit inside, but I only have brick-like power banks, and I'm a bit torn about whether to also be compatible with direct USB-C power supply. Everyone is welcome to leave a comment with your power bank brand, and I'll consider whether to fit the most popular sizes inside or keep them external

This time, I still want to thank Pengpeng's General Store for providing the controller files, which made modeling much simpler. For everyone's convenience, I'll still post the purchase links for the accessories below

If you want anti-slip, you can stick this to the bottom, covering the screw holes. The groove is made according to this size

Also, if someone is really too lazy to print it, you can search for "Shisan'er" on Xiaohongshu to buy the kit directly
