Pixel Strip Labels
thingiverse
There are two versions uploaded. One with a blank face(StripLabelBlank) and one with the number 12(StripLabelText, which can be customized using instructions below): To customize the number(text), open PixelStripLabel.f3d in Fusion360, drop down Sketches on the left and right click on Sketch2>Edit Sketch. From there you can double click the number and change it to whatever you want. I have not printed out a version with numbers so I am not sure what support settings you will need. I test fit this on HolidayCoro pixnode strips but am unsure about other styles.
With this file you will be able to print Pixel Strip Labels with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Pixel Strip Labels.
