Delta Printer Electronics Cooling Unit

thingiverse

A custom duct system is being designed for a massive Delta Printer that stands over one meter tall, utilizing 455 mm 2020 horizontal extrusions (RobotDigg 2040 corners) to create a robust structure. The housing will securely mount a Beaglebone Black and Replicape on an aluminum plate that functions as a heat sink for the power supply and SSR, located beneath the heated bed. A fan conduit is carefully designed to accommodate two 30mm x 30mm x 10mm fans, which will push air across the printer controller and stepper drivers, effectively isolating them from the heated bed and stepper motors. Two sets of fan grills are attached to the inside of 2020 extrusions using M3 screws, while grill covers mount on the exterior with M5 x 8mm screws. It is essential to have an ample supply of M3 screws to ensure a secure assembly. The fan wiring may require the use of a Dremel until an efficient wire path can be planned, with consideration given to a subtle notch on the top conduit cover. Two Sunon 30mm fans, part # MC30101V2-000U-A99, are used for this design, boasting specs of 4.6 CFM, which should provide more than adequate airflow when used in parallel.
