Jerlo SKR Box Bear with Noctua FAN

Here is a great design for the development of the SKR 1.4 card for the BEAR frame

I designed this model for many advantages:

• Simplify the maintenance of the electrical part with a door on the outside

• Ventilation of the motor drivers by 2 Noctua fan 40x40mm

• Optimize the cable routing

• Indicate the polarities of the devices

• Fix an ESP01 for WIFI

• Fix the door by neodymium magnet 3x8mm

• Thickness of the box is equal to the thickness of the bear frame

• Compatible with version SKR 1.3 but pay attention to the polarity engraved on the box which can be different on certain objects

• Compatible with my bear feet https://www.prusaprinters.org/prints/10510-bear-paw

• SD card holder at the back of the box

• Reset button for fast reboot

Screws :

• Ring_Base : 2xM3x16mm
• Cable_Bed_fixation : 2xM3x16mm
• Card fixation to the box : 4xM3x10mm
• Attaching the base to the bear frame : 2xM5x10mm

I advise you to print each piece separately

Use the "spacer" between the M3x10mm screws and the SKR card so that the screws do not protrude from the side of the heating bed
