Fader Caps for Traktor Kontrol Z1

I made these to have the faders more visually present in the dark. Therefore, I printed the faders with GlowInTheDark PLA Filament. The mounting holes on the bottom side took some experimenting before they exactly fit the Z1 faders. If you have a different controller, give it a try and if they don't fit, changing the hole dimensions is an easy task.
