This is a PSU case with mounting holes designed specifically for the Chinese 500W spindle PSU available on AliExpress, Bangood, and Gearbest. Hardware Used: My particular PSU came from Bangood: https://www.banggood.com/Machifit-ER11-Chuck-CNC-500W-Spindle-Motor-with-52mm-Clamps-and-Power-Supply-Speed-Governor-p-1027937.html?rmmds=myorder&cur_warehouse=CN Power Plug Used: I utilized the following power plug: https://www.amazon.de/gp/product/B01H5MK3OI/ref=ppx_yo_dt_b_asin_title_o03_s01?ie=UTF8&psc=1 Warning: Not all Chinese spindle PSU's are created equal. Some may be larger, while others are smaller. It is crucial to check the sizes before printing. ~Size (H x L x W) (TOTAL) (Based on Fusion360): 55.5mm x 185mm x 121.40mm Sizes: To minimize printing time, the walls have a width of 1.5mm (final result may vary based on filament and other factors). This means the walls are relatively thin. This only matters for the single standing wall where the PSU is fixed in place with screws. All other walls are robust because they are connected to each other. When the PSU is mounted, the entire case becomes strong. Sizes/Dimensions: The three larger holes you can see are 10mm. These can be used either to mount the potentiometer or to get cables in/out. Size available for PSU (H x L x W) (Based on Fusion360): 51.50mm x 183mm x 98.40mm The actual length the PSU is supposed to use is approximately 132 mm. The rest is allocated for cables, a potentiometer, and a power socket. Holes for the PSU are 3mm. Holes for mounting the case on something are 5 mm (See images) Hole for the power socket is 48mm x 28mm (W x H). Screw holes for the power socket are 40mm apart. 1.780 mm left from the center, and 6 mm above/below the large cutout. Screw hole size is 3.8 mm (4mm screw). See images for PSU screw placement.
