Ok. Here goes.
Didn't like the idea of not being able to distinguish my Noisy Cricket from all of the others. Actually had a run-in, at a local shop, where it came down to checking the dripper and even the flavor to figure the whole thing out. Solved that problem with a Copper Saline Etch and the vinyl cutter that I typically use for airbrushing (another passion) masking and sign/sticker making.
Wanted a more elegant way of keeping my batteries distinguishable. Each set is married, numbered, and rotate together, except for the Harley Quinn ones, which I rotate through my single battery mechs.
The manager of one of the local shops wanted a Buddha Z V3, but he hated the chuff cap that comes with it. So, I turned this out of some delrin I had from a previous project and I don't think he could've been happier.
I guess the bottom line is I love to tinker and work with my hands. I've recently started selling sets of the Framed Staple Coils I showed in my first post at the local shop. Love having an outlet for creative energies...idle hands get me into trouble.
