The New Hotness

I cut some transparent acrylic pencil guides to go along with the 45° Triangle Ruler:

The guides along the rear are the 3D printed versions from a decade ago.

The three transparent guides taught us:

• 4 mm is better than 3 mm
• Entirely transparent guides vanish on the table

So the engraved ring on the two in the front row carries a cheerful Sharpie color to make them stand out. I wanted to use fluorescent acrylic, but I don’t have any 4 mm sheets and stacking a pair of 3 mm sheets → 6 mm will be too thick for the pencil tip.

What looks like dirt on the red guide comes from internal reflections or the lack thereof: it’s perfectly transparent in person, honest.
