19cm(7.5'') Seven Segment Display

thingiverse

Hi! This is my first upload to Thingiverse and my version of homemade 7-segment displays. The dimensions are 190mmx100mmx10mm. There are two designs for the base of the display, both basically the same but with a key difference: one has an initial layer (0.3mm) covering the whole surface. I added this layer because I had problems with sticking filament on those small squares and circles. To fix it, you'll need to manually cut them out - a simple task. I use red LED strips (3528) that are cut to length to fit inside the segments. These strips can be connected directly to a PCB or using classic wires via 2.54mm right-angle male pin headers. For the decimal point, I opt for a 5mm red LED diode. To assemble your 7-segment display, follow these steps: Print one of the two base designs (either 7_segment_1.stl or 7_segment_2.stl) in black. Print a single decimal point module from the decimal_point.stl file also in black. Print seven cover pieces from the cover.stl file - they should be white. Finally, print a single cover for the decimal point from the decimal_point_cover.stl file and again in white.
