"Its not so much about age as quality."
I know how that feels ;)

I do use those standoff's for some projects.

I think heat might be a factor too, but with low power stuff, not much of an issue.

I was just thinking, a small diameter wooden or plastic dowel with a hole in the top and a tight fitting push in 2-56 screw might work as well.

Edit
Agree, the clear cable ties do not like UV.

Maybe a modified version of this would work too:

The Arduino designers made major mistakes in the placement of the mounting holes.
These were placed too close to headers etc.
Well, it was more like they added additional headers after the screw holes had already been fixed in place.  Go back to the duemilanove (or even the Uno V1), and there's plenty of room around the mounting holes.

I avoided that problem by cannabilizing a cheap plastic Arduino enclosure to use as the mount.  Too much trouble to try to keep four holes perfectly placed.  This way I only need two holes for the enclosure itself and there's play for slight adjustments.

I have used old biro tubes cut to length in the past , there is a bit of slop to allow some mis alignment betwen hand drilled holes as well.

A few hints on making 'Infinity Mirrors'.
One ProMini, some code, 47 neopixels, acrylic frame and some woodworking skills can result in a nice gift idea (or 6).

I made an infinity mirror with my sister, it was a lot of fun. Put it down on the floor and it just looks so weird. What I want to make next (one of a couple "above and beyond" enhancements of old projects I've done) is make an infinity digital clock with APA120s embedded into the mirror so I can do some color-fading effects with the time display and border LEDs.

The most ugly thing about most RGB LED strips is the discreteness of the individual LEDs. From a close enough distance, your eyes can clearly perceive the spacial difference between light spots. has anyone found a good tactic for diffusing individual SMD LEDs? I'm thinking of trying a very small blob of hot glue and seeing if that takes the edge off it. It's slightly translucent.

Sometimes a simple tool will do just fine.
