3-1/2 in Deck Baluster Spacing Gauge
This is a hook-on spacer block for building deck railings. It is exactly 89 mm (3-1/2 in) wide, so every gap comes out the same and stays under the common 4 in sphere rule. The 25 mm lip hooks over the top of the rail, so the block hangs between face-mounted balusters while you screw the next one in. It is a ribbed open frame (89 x 110 x 20 mm body) with a finger hole for pulling it back out.
Framing Square Stair Gauge Pair
A pair of 28 mm stair gauge knobs that clamp onto the edge of any steel or aluminium framing square. Each has a 5 mm slot that takes blades up to about 4.5 mm thick, plus an M5 thumb screw and a drop-in captive M5 nut. Set one gauge at the rise and one at the run, and every stringer notch, rafter seat or repeated angle transfers identically. They print as two knobs joined by a snap-off sprue bar.
150 mm Metric Rafter Speed Square
A 150 mm metric speed (rafter) square. The 12 mm lip hooks over a board edge so you can mark square cuts. It has engraved degree ticks every 5° swinging from the pivot corner, a mm scale every 10 mm, and 3 mm scribe holes 20–120 mm in from the fence for drawing parallel lines with a pencil or scribe. The open-frame triangle keeps it to about 43 cm³ and prints flat with no supports.
