Raspberry Pi mounting bracket (for FFCP)

thingiverse

This is a versatile mount intended for installing a Raspberry Pi inside a FlashForge Creator Pro or similar printers, where it can thrive without the need for an extra case. The mount was designed specifically for placing the Pi at the front of the underside of the printer, next to the power supply, ensuring optimal placement for the WiFi antenna on later Pi models that are prone to signal reception issues due to being sandwiched between metal plates. This location also offers practicality in routing wires to other parts of the printer, especially when utilizing the Pi for adding variable fan speed control. The brackets were designed with model 3B in mind but should theoretically fit any model. The design utilizes 2.2x6.5 mm self-tapping screws, requiring only two due to the Pi sliding into the rear notches of the mount. Epoxy glue is recommended for attaching the brackets to the printer, as it allows for a 5-minute curing time, providing ample opportunity to tweak the position before it hardens completely. Any other suitable adhesive can be used in its place, or double-sided adhesive tape can be employed if it maintains its stickiness over time. Place the Pi sufficiently to the left to leave room for inserting USB plugs. It is advisable to glue the brackets with the Pi inside and any potential mounting issues plugged into the Pi before applying the adhesive, ensuring a smooth fit prior to curing. There are two models available: one raises the Pi 23 mm from the bottom, striking a balance between accommodating wires connected to GPIO pins and minimizing microUSB power cable bending. This model is best suited for applications where the power cable is not highly flexible. Low-profile or angled header plugs will be necessary for the GPIO pins in this configuration. The other model elevates the Pi 19 mm from the bottom, providing more room for GPIO plugs but necessitating a small microUSB power plug with a flexible cable. To power the Pi, refrain from attempting to siphon 5V from the printer's main board, as it lacks sufficient current delivery. Instead, utilize a compact USB power supply that can be tucked under other printer wires. When connecting your USB supply to mains, consider cutting off an extension cord and attaching its wires to the printer's power supply terminals. This setup is safe, ensuring the Pi powers on and off with the printer. However, always prioritize a clean shutdown of the Pi before disconnecting its power source.
