Test strip maker with 7 segments

Last crawled date: 5 years, 9 months ago

Most existing test strip makers seem to be designed around 6 segments. Since my enlarger timer's test strip mode does 7 segments (RH Designs Analyser Pro), I wanted something that could do the same. This design is similar to some existing test strip makers I've seen, and is approximately 7.5" wide (to fit across an 8x10 easel area).
It also has holes for magnets, sized around McMaster-Carr part 7048T22.
