Did these last year, and just encountered them again when we decorated.
Gather some acrylic scrap and give these a try… edgelit by the bulb. Just grab your calipers and measure for the bulbs you have. I have two different sizes on the strings we have accumulated.
The yellow is frosted, but I think the clear works best for this.
If I had it to do over again I would engrave the inner cutouts on each arm instead of cutting them out. I’m going to have to whoop up another one to see if I like it better.
