18650 Four-Bay Screw-Contact Test Sled
A sled that holds four 18650 cells (18.4 x 65 mm) in 19 mm open-top troughs on a 24 mm pitch, so you can test, balance or capacity-check salvaged cells without spot-welding. Each end wall takes an M3 brass heat-set insert (4.0 mm bore) on the cell axis. An M3 screw threads in to clamp the cell and make contact, with 3 mm of travel at each end. Footprint 100 x 87 mm, 20 mm tall.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
Pi HAT Pogo Pin Test Jig Base
A 96 x 80 x 14 mm pogo pin test jig base for Raspberry Pi HAT and pHAT boards. It has M2.5 locator holes on the 58 x 49 mm and 58 x 23 mm Pi patterns, and a 2.54 mm drill-guide grid (21 x 17 lines) where you drill holes to fit your own pogo pins. Four M3 heat-set bosses take a hold-down lid, and a raised skirt with a cable notch gives wire clearance underneath. It saves you from hand-holding probes every time you retest a homebrew board.
