A holder for Baader Planetarium (and similar) solar film. Designed for a Skywatcher 80ED (outer diameter = 116mm). If you are interested in on for a different telescope, message me and I can provide edits!
The body and clamp should be printed in PETG / ABS for flexibility. The cap and plug can be printed in PLA. Countersunk M3 screws will self-tap into the body.
