Ebay / Aliexpress (LCR-T4) Transistor Tester Case (Minimalist)
Description
This is a minimalist "case" for the common LCR-T4 transistor tester from Aliexpress and eBay. It is a single piece, and very quick and easy to print with any setup. I have tried to keep it as simple as possible. I have chosen to use heatstakes to attach the board. This does not seem common with 3D prints and I don't know why. It is quick an easy to print and attaches the board with no additional fasteners. It does fasten the board permanently, but this OK for something like this. I never intend to remove it from the case. This would be an issue with a DIY project that I might want to take in and out of the case while debugging. Plus it is easy to reprint this if I have to cut it out of the case at some point. After placing the board on the standoffs about 2mm of plastic should stick out of the mounting hole. Heat a flat piece of metal such as a utility knife or the back of a pair of tweezers with a lighter for about 10 seconds then press it on the excess plastic. It will melt into / around the hole. Hold it for a few seconds until the plastic hardens. It will hold the board firmly. It takes a couple tries to get the hang to the technique to melt these on. But it can be done reliably once you get the hang of it.
