Tonight's insomniac muse brings you a geared AAA battery holder. At some point, I might actually animate this. Has been print verified. No picture available because I used this spool of really bad blue filament that I've been using up for prints that I don't care if they come out flawed. I do wish there was a bit more product consistancy among the manufacturers. Anyone happen to find a product line that is always good? Have a great day. Bill.
