EMT Conduit Pendulum Bend Angle Gauge
A pendulum protractor for checking conduit bends. Its 90° V-foot sits on 1/2" EMT (17.9 mm OD) or 3/4" EMT (23.4 mm OD) and is held on by a rubber band or zip tie through two slots. A swinging pointer, printed in place, reads ticks every 15° (longer ones at 0°, 45° and 90°) in either direction, so you can check 22.5°, 45° and 90° stub-up bends while the conduit is still in the bender. The part is 126 x 114 x 32 mm, and you can drop an M5 bolt and nut into the bob's 5.5 mm hole to add weight so the pointer settles faster.
1/2, 3/4, 1 in Knockout Blank Plug Set
A set of three snap-in blanking plugs for unused electrical knockouts: 1/2 in trade (22.2 mm hole), 3/4 in trade (27.8 mm) and 1 in trade (34.5 mm). They print on one snap-off sprue about 121 mm long. Slotted spring fingers with a 45° barb push in from the front, grip steel box and panel walls about 1–2 mm thick, and leave a flush flange 4 mm wider than the hole on every side.
Four-Bay Wire Nut Scoop Caddy
A 144 x 70 x 28 mm caddy with four bays that get wider from left to right (26, 30, 36 and 42 mm). Sort twist-on wire connectors by size, from grey and blue up to yellow and red, so you stop digging through a loose bag halfway through a job. Each bay has a 45° scoop ramp at the front so you can slide a connector out with one finger, and two 4.5 mm holes let you screw the caddy to a bench, a cabinet door or a truck drawer.
Outlet Box Drywall Setback Gauge
A flat 120 x 45 x 6 mm step gauge for setting new-work electrical boxes flush with the finished wall. Three notches set the box's projection past the stud face at exactly 9.5, 12.7 and 15.9 mm (3/8, 1/2 and 5/8 in drywall); dimples next to each notch (1, 2, 3) show which is which. Rest the land on the stud, slide the box forward until its rim touches the back of the notch, then nail it, so you don't end up with recessed boxes that need box extenders.
