 +=== Dimensions ===
 +
 +The aluminum (or acrylic) front panel of MIDIbox Quad Genesis is 15" x 11" (38.1 x 27.9 cm), and the front panel PCB itself is 13.85" x 9.85" (35.18 x 25.02 cm), leaving a 0.57" (1.45 cm) border around the edge. The aluminum I used was 1/16" (0.062"​ or 1.57 mm); this may be a consideration if you use acrylic which is much thicker (2mm should probably be fine but 3mm might be a problem, with the 3D printed buttons - **Update** - Smithy has provided modified files for 3D printed buttons and light pipes to fit 3mm panels below. ).
 +
 +The spacing between the underside of the front panel and the upper side of the PCB is about 0.27" (7 mm), which is originally defined by the encoders and the 3D printed buttons are made to match this. I used 1/4" nylon spacers/​standoffs from eBay plus a flat washer (4-40 or M3) to achieve this spacing. I used 0.75" 4-40 screws to put together the front panel, in which case the depth of the assembly was 0.75" with the electrolytic capacitors and pin header / IDC connector sticking out past this. The panel and PCB can be fastened together with 4-40 or M3 screws.

 +
 +===== 3D Printed Front Panel =====
 +Smithy has provided an STL file for a 2mm 3D Printed Front Panel with 1mm Raised Lettering as a more budget friendly option. It will require a printer with a bed side size typically of 400 x 400mm or larger.
 +This is currently untested and unprinted, and may require a resolution / layer height setting of 0.1mm to be accurate. More info to come when I have  designed and 3D printed and a Rear Panel.
 +Please see the following guide to achieve a dual colour panel with a different colour for the lettering and for the panel:

 For Color fields, as discussed above, you may change the colors to whatever you want, but it is recommended to keep the colors consistent (e.g. make everything "​green"​ below be the same color, and everything "​red"​ below be a different color). For the Red/Green buttons below, the Red LED is always on the left and the Green LED is always on the right. For Color fields, as discussed above, you may change the colors to whatever you want, but it is recommended to keep the colors consistent (e.g. make everything "​green"​ below be the same color, and everything "​red"​ below be a different color).
