Hiland M644 transistor tester case

Hiland M644 transistor tester case

thingiverse

I modified another case designed by "egil" http://www.thingiverse.com/thing:1580922 to use for the Hiland M644, together with a 18650 dual battery holder. The 2x 18650's in series supply between 7V and 8V, which is enough for this tester. It is probably a good idea to fit a small BMS protection board to balance the 2 batteries. I used the cap from a toothpaste tube for the knob, it works for me. ;) I used "wood" PLA and varnished it afterwards.
