MAIN PURPOSE: Tuck fabric into furniture frames
A flat, tapering blade on a round handle for pushing fabric, leather and wadding into the gap between seat and frame, with a notch in the tip for guiding piping cord: firm enough to push, smooth enough not to snag or scratch show wood.

Print in PETG or nylon and sand the blade edge smooth. Prints flat as a plate, no supports.
MAIN PURPOSE: Match string height to the fingerboard radius
Each side of the square is a concave arc: 7.25, 9.5, 12 and 16 inch radius. Sit it on the fingerboard to identify the radius, then under the strings to set the saddle heights to the same curve, so every string has the same action.

MAIN PURPOSE: Mark where a picture hook must go
Hang the picture's wire or cord in the notch, push a panel pin through the hole just below it, then hold the picture where it should go and press: the pin pricks the exact spot for the hook, so the picture hangs where you held it, first time, with no measuring.

MAIN PURPOSE: Draw lines parallel to a board edge
Hook the fence over a board edge and run a pencil in one of the six holes: they sit 5, 10, 15, 20, 25 and 30 mm from the fence, so you draw a parallel line for a rebate, a hinge or a row of screws in one stroke without measuring twice. Print it as shown, then turn it over so the floor becomes the top.

MAIN PURPOSE: Set honing guide projection repeatably
Hook a side-clamp honing guide over the low front wall and slide the blade forward until it touches a stop block: the four stepped blocks set 32, 38, 42 and 50 mm of projection, the settings for 25 and 30 degree bevels on plane irons and chisels in an Eclipse-pattern guide. Every resharpening lands on the same angle.

MAIN PURPOSE: Find the centre of round stock
Press a round turning blank, a dowel or a log end into the 90 degree V and draw along the blade, whose edge lies exactly on the bisector; turn the blank a quarter and draw again. The lines cross at the true centre, ready for the drive spur, a chuck or a drill.

MAIN PURPOSE: Clamp panel glue-ups evenly across their width
Each caul has a 1.5 mm crown along its working face: clamp a pair across a panel at the ends and the crown presses the middle first, so the whole joint closes evenly instead of gaping in the centre. Print four, two for each side of the panel.

MAIN PURPOSE: Stop a saw kerf closing on the blade
When ripping a long board by hand, tap the wedge into the kerf behind the saw: it holds the cut open from 1.5 to 6 mm, so the wood cannot close and pinch the blade, and the saw keeps running free and straight to the end of the cut.

MAIN PURPOSE: Detect twist in a board before planing
Set one stick across each end of a board and sight across their top edges: if the edges are not parallel, the board is in wind, and you can see exactly which corners to plane down. Print one stick in a light colour and one in a dark colour so the edges stand out against each other.

MAIN PURPOSE: Clamp work to the bench in a quarter turn
Bolt the cam to the bench through its off-centre hole with an M8 bolt, set the work against a stop and swing the lever: the cam's growing radius wedges the piece tight in a quarter turn, and a flick back releases it. Two cams and a batten make a quick planing or routing fixture.
