Housing to take a Ruideng DPH5005 boost/buck board and screen and power it from a Makita 18V LXT battery to give you a portable benchtop power supply with a range of 0-50V and 0-5A. Other Ruideng boards could be made to fit I'm sure. The main circuit board is fitted to the nylon standoffs that came with the board.
Stainless steel self tappers hold the front and end plates on and I fitted a rocker switch in the back plate to turn off power to the main board. I fitted a 10A fuse between the battery and the Ruideng board.
I used 2.2mm aluminium sheet for the infill, you might need to adjust the gaps for these in each part to suit whatever plate you're using. I've made the gaps 2.4mm in the part file which worked well for me in PLA.
The connection the battery is using my own design of Makita socket adaptor which fits the Makita OEM battery connector, see http://www.thingiverse.com/thing:3757918
