Aniprinter - The anime printer :3

Anime printer!!! I’m gonna add some cat ears lol

Made by: @Cyao

Respository link: https://github.com/cheyao/aniprinter

Hours so far: 75.5h

• I have a bambu A1 mini and access to larger school printers

Printer for my ani* set of hardware!

The plan

I don’t fucking know but I’ll figure it out in the vacations. I never failed anything when money isn’t a constraint :D

1. Hella cheap
2. Capable of printing figurines
3. 310x310x310+mm
4. Cute & colorful
5. Have removable cat ears on it :3 (Dad’s killing me if he sees cat ears TwT)
6. Multicolor!!! 8+ colors! Extra: Be able to print some metalic filament, that would be soo cool

How to source the parts cheaply? I’m buying everything from china lol

Currently the outline is 400mm x 410mm

Rant

Today I’m looking at YT vids of printers, they look fucking complex. But thats where the fun lies :P.

Ok fuck tutorials I’m going in blind

Note: motherboard uses JST-XH connectors
