I wanted something to hold the battery in place on my LCR-T4, but didn't want to spend the time printing one of the (very neat-looking) full cases available on here, so I designed this skeleton case. You will need: 12g filament 2 shorter 3mm screws (about 6mm of thread) 2 longer 3mm screws (about 10mm of thread) An LCR-T4 (I bought from eBay seller wgd0947) 9V battery Mount the LCR-T4 to the A part using the two lower screw holes, making sure you route the battery wire between the PCB and the skeleton so it comes out in the location shown in the pictures. Iert a battery into the B part (hook the terminals in fit) with the terminals oriented to match the battery clip, then use the longer screws to affix to the back of part A.
