E12 Resistor Twelve-Slot Index Box
A 105 x 55 mm box with 12 slots, one for each E12 value (10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82). Each slot is 7 mm wide and 51 mm deep and holds small poly bags or taped strips of that value, one bag per decade. The front of each slot has 1 to 12 moulded dots, so you can find a value by counting, with no printed labels to smudge or peel. The top slopes from 45 mm at the back to 28 mm at the front, which leaves the bag tops easy to read and grab.
Axial Lead Bending Pitch Jig
A 136 x 26 x 14 mm bench jig for forming the leads of axial through-hole parts (1/4 W resistors, diodes, small caps) to exact PCB hole pitch: lay the body across a rib, press both leads down the sides, and the lead centres land on the 2.54 mm grid. Six ribs give 5.08, 7.62, 10.16, 12.7, 15.24 and 20.32 mm (0.2–0.8 in) pitches — each rib is milled 0.6 mm under its pitch so the bent lead diameter makes up the difference — with 3 mm relief slots through the 4 mm base so long leads pass clear, and two M3 clearance holes 122 mm apart for bolting it to the bench.
