Nickel Strip Three-Roll Braked Dispenser
A bench dispenser for up to three rolls of battery nickel strip, up to 76 mm OD, on a slide-through 8 mm steel rod. Each lane has a 12.5 mm wide exit slot that takes 8–12 mm strip, plus a 1.6 mm flexure tongue tightened from above by an M3 screw. The tongue acts as an adjustable drag brake, so the strip feeds flat and won't spring loose or kink while you build 18650/21700 packs.
Flagged: hydraulic brake system. Not for safety-critical use without independent engineering review.
18650 4x5 Spot-Weld Grid Jig
A 20-cell spot-welding jig for building battery packs (for example 4S5P or 5S4P) from 18650 cells (18.4 x 65 mm). The 18.9 mm pockets sit on a 20.5 mm pitch with 1.6 mm webs, so the cells stand square and evenly spaced. The jig is 108 x 104 x 14 mm. A 14 mm hole in each pocket floor lets you push the cells out. A side ledge has an end stop and cut grooves at 20.5 mm steps, so every nickel strip comes out the same length. Print two, one to cap each end of the pack.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
