Case for AVR component tester

thingiverse

This project utilizes a custom variant of the popular universal transistor and component tester designed by Markus Frejek and later Karl-Heinz Kübbeler. For detailed information on this project, visit http://mikrocontroller.net/articles/AVR_Transistortester. A suitable kit can be obtained from Banggood through their product listing at http://www.banggood.com/DIY-Meter-Tester-Kit-For-Capacitance-ESR-Inductance-Resistor-NPN-PNP-p-929603.html. The project's case has two versions, one featuring M3 countersunk screw holes and the other a snap lock design with an internal structure allowing for screws to be added later. Two variations of the button are also available: one features a collar fitting over the switch, while the other is flat. Cases compatible with larger graphical displays can be found at http://www.thingiverse.com/thing:797733 here: http://www.thingiverse.com/thing:694790 here: http://www.thingiverse.com/thing:1580922 and also here: http://www.thingiverse.com/thing:1920077. The printing process is quite straightforward, requiring no supports or minimal cleanup effort when printed using PLA. However, for best results the first layer must be set up accurately to avoid potential cleanup efforts later on.
