RD DPH3205 buck/boost power supply case - banggood, alibaba

thingiverse

Nov 2019 Update: This has been adapted to run from a Milwaukee M18 battery pack. As the DPH3205 is a buck-boost, it can handle various voltages as the pack depletes, but there's no protection circuit to safeguard the pack from low voltage. The Milwaukee adapter prints as a separate unit for gluing on; however, I will eventually create a single printable unit. Simple case design for power supply modules found on Alibaba and Banggood here. This was designed for that module, but others in the series appear to be the same size. Total dimensions of the box are 120 x 80 x 80mm. 4mm banana plugs are used for input and output with an additional hole for an XT60 output plug. The rear panel is a simple piece that clips into place without requiring screws. It also contains a duct for the fan, and nothing is attached to it so assembly can be completed inside the main box before the cover is clipped on the back. Print Settings: Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: 0.2mm Notes: Print at 35mm/sec, 220 degrees, 0.2mm layer height, and 0.4mm nozzle - approximately 10 hours plus 2 hours. The box walls are 2mm thick, so print with 1.2mm walls to force solid walls to be created. Print the front of the box face down; you shouldn't need any support. You may have to slightly clean up the inside of the XT60 hole depending on how well your printer bridges. Post-Printing: There's not much post-processing needed. You might need to slightly enlarge the window for the control unit (personally just vertically). The XT60 plug is a very tight fit, so I sanded the plug itself until it fits snugly without needing glue or fasteners. The back panel was designed as a tight fit, and the case's flexibility allows it to clip in easily. I managed to avoid any post-processing on this one. Add some nice rubber feet to the base for better stability.
