Bezel for 2x 8 Digit 7 Segment LED Modules (MAX7219)

cults3d

This is a panel mount display bezel designed for two 8 Digit 7 Segment Display Modules controlled by MAX7219 chipsets. It includes a recess for a 65mm x 35mm x 3mm window, which I made from a piece of dark/smoked Perspex acrylic sheet. There are four mounting holes for each display module, designed to accept M3 screws (you only really need two screws in the diagonally opposite corners of each display). The LED displays clamp the window firmly into place (don't overtighten the screws, they should just be snug to the PCB). The parts I used were: * 2x 8 Digit 7 Segment LED Display Modules with MAX7219 controllers * Smoked perspex sheet 65mm x 35mm x 3mm * 8x screws M3 x 8 socket headed button screws Clean out the holes with a 2.5mm drill bit, and the M3 screws will self-tap into the holes fairly easily. Here's a link to the display modules I used: https://www.amazon.co.uk/dp/B07CKSKNGW The LED modules are approximately 82mm long, 15mm wide, with mounting holes about 76.5mm x 9mm apart and 3.6mm in diameter. The LED display is not centered on the PCB, and the gap from the LED module to each end of the PCB measures about 12.6mm at the left side and 9mm at the right side.
