Print-In-Place Contour Profile Gauge
A print-in-place contour (profile) gauge: 27 sliding pins on a 3.2 mm pitch copy an 86 mm wide profile up to 26 mm deep, so you can trace pipe, moulding, skirting or a tile cut-out straight onto the workpiece. Body is 110 x 18 x 48 mm with a 5.5 mm M5 clearance hole through one end post for hanging on a nail or pegboard hook; pins print standing on the bed inside a closed channel and drop to full extension when you hold it pin-side down.
Print-In-Place Ellipse Drawing Trammel
A trammel of Archimedes that draws true ellipses for oval cutouts (speaker holes, van ports, arched panels) — a 150 mm cross base with two crossing T-slots, two captive sliders and a 120 mm beam, all printed as one assembled 4-piece mechanism with 0.4 mm running clearance. Pin spacing is 45 mm; eight 8.0 mm pencil holes along the beam give ellipses from 18 x 72 mm up to 96 x 186 mm overall, and four 4.5 mm holes (M4 clearance) at the arm tips let you screw or tape the base to the panel.
