I’m using a small set of 7 seg leds - I could do with a small red filter to fit on the front of it - any ideas , only stuff I’ve found is very expensive ? something with bezel would be ok too ! 4*0.36”

2423 deep red acrylic sheets in 3mm (1/8") thickness are pretty cheap and common. Even Amazon has them. The thinner 1/16" sheets are much harder to find.

Take a clear piece of plastic sheet (old CD case), carefully add good quality double stick tape to the surface avoiding air bubbles. Source from a hobby store, add red cellophane to tape avoiding air bubbles again.
