Chassis Layout Designer

Pick the preferred material and model, then simply add holes to your chassis, naming each hole. The panel below shows the top of the chassis flattened out with the front and back walls unfolded above and below it, so holes for potentiometers on those walls can be placed the same way as holes on the top. Holes sizes and recommendations are a guide, you can find any measurements you need from other parts on the products page for each e,g, you may prefer under chassis sockets which are different sizing to the standard 18mm. 

 

Recommended hole sizing

 

# Label Panel Diameter (mm) From bottom (mm) From nearest side (mm)  
No holes yet — click "Add hole" to place one.

Distances are measured to the exact centre of each hole (marked with a black dot), from the bottom edge and nearest side of whichever panel that hole is actually on — Front Panel, Top Panel, or Back Panel — shown in the Panel column. Because the Back Panel is drawn upside down (it's the far side of the chassis, unfolded), its hole names and measurements are shown upside down too, so they read correctly once that panel is viewed the right way up. Diameter and both distance fields are editable; holes are kept at least 5 mm apart and inside the outline automatically.
