This is a simple enclosure for a 7 digit resistor decade with thumb encoders. You can find more information about the concept and the schematics on the EEV blog http://www.eevblog.com/forum/projects/diy-cheap-resistor-decade-substitution-box/
It's really great and helpful both for development or education, especially when you're designing opamp designs, filters or audio amps. You can adjust any resistance value from 0 up to 9,999 MOhms. The tolerance depends on the quality of the resistors, but 1% types should do fine for most applications.
The enclosure itself consists of two parts. You just need four M2.5x10 mm screws (or an equivalent inch-size) for the cover and two 4mm banana jacks.
