This thing has three main purposes:

1- Protects the Ender 3 main board cooling fan from dust and debris. 2- Serves as a case for a Raspberry Pi 3- Use the Ender 3 electronic enclosure cooling fan to cool the Raspberry Pi

Four objects to print:

1- Main body 2- Attachment 3- Two of the Raspberry latches

Installation:

Remove both front screws from the top cover of the electronic enclosure and set aside. Assemble the main body and the attachment part. Then install the Raspberry Pi and secure it with both Raspberry latches. Slide the assembly from the back until the hooks grab the frame and use the original screws to complete the assembly.

All files can be printed at once on the Ender 3's bed without support material.

No hardware needed!
