Printer Power Supply cover for integrated switch fuse plug

thingiverse

Power supply cover for 20A, 12VDC Mean Well style power supply as originally supplied with the Tronxy P802E printer. The cover protects the mains and accommodates an integrated switch/fuse/modular cord unit. To obtain this unit, search Ebay for "3D Printer Makerbot Ultimaker Accessory Parts 3 in 1 Fuse Power Supply Socket". Typically priced at about $1.50 USD shipped, but you will need to provide your own 2A micro fuse and PC cord. Mounting is achieved using 11mm long standoffs that are often spare parts left over from printer assembly or can be printed from a file. The back plate creates a wrap-around design so the cover can be securely attached to the supply, then mounted to the printer using 11mm standoffs to the printer frame. When the power supply is mounted vertically on the right side of the printer, the cord exits at the rear. Good ventilation is provided through an opening in the lower front and a honeycomb design on one side. A picture also shows how I modified the excessively noisy fan with a larger PC fan, resulting in significant noise reduction. This design has been superseded by V2, which can be found here: https://www.thingiverse.com/thing:2524688
