eVscope telescope solarfilter holder
With print you need also solarfilter:

I laminated the filter which protects it from scratches and accidental holes, but it's not necessary. Laminated filter stays in between holder parts without glue, so does unlaminated filter because parts fit together so tightly.
NEVER USE A BROKEN FILTER!
