Rotary-Disc Lettering Guideline Template
This is an Ames-style lettering guide: a 120 x 80 x 4 mm frame holding a 65 mm disc that prints in place and turns freely. The disc has three columns of 1.6 mm pencil holes: an even 4 mm pitch, a 3/5 lowercase ratio and a 2/3 ratio. Turn it to an index tick to set guideline spacing at 4, 3.5, 3, 2.5 or 2 mm, then put a 0.5 mm pencil in a hole and slide the frame along a T-square or ruler. The frame's 68° slant edge and 90° edge draw italic and upright slant lines.
145 mm Raised Ink-Edge French Curve
A 145 x 78 x 3.2 mm drafting French curve for drawing smooth curves. The outer edge changes curvature continuously, and it has an inner ellipse slot (36 x 16 mm), a 20 mm circle cutout and a 7 mm hang hole. The outer edge sits on a 2.5 mm inset step 1 mm tall, so it rides above the paper and technical pens or fineliners don't wick ink underneath and smear.
Maker Circle And Hex Nut Drafting Template
This 170 x 70 mm drafting stencil lets you sketch enclosures, brackets and panels at 1:1 scale. It has circles from 2 to 14 mm, 1:1 outlines of 624, 625 and 608 bearings (13, 16 and 22 mm), and outlines of M3, M4 and M5 hex nuts (5.5, 7 and 8 mm across flats). Each opening is cut 0.6 mm over nominal so a 0.5 mm pencil traces the true size. The circles have centre-line notches, one edge has a scale notch every 5 mm, and two raised rails underneath hold the stencil off the paper so ink doesn't smear.
1 in Pitch DIY Pegboard Drilling Template
A 116 x 66 mm drill guide for making your own pegboard from plywood or MDF. It drills 15 holes at a time on the standard 1 in (25.4 mm) pegboard grid, and each 1/4 in (6.35 mm) bit runs through a 6.6 mm bore in a 14 mm-tall guide boss. To step along the board, drop a spare 1/4 in bit through one of the end bosses into a hole you've already drilled. The sighting notches and windows let you line the template up with pencil layout lines.
Four-Radius Corner Rounding Template
A 100 x 100 x 4 mm hooked template with a different corner on each side: 1/4 in (6.35 mm), 1/2 in (12.7 mm), 3/4 in (19.05 mm) and 1 in (25.4 mm). Hook the 6 mm fence lips over the corner of a board or panel, then trace or flush-trim the arc so every corner of a shelf, lid or plate comes out the same. Through-holes next to each corner (one dot for the smallest radius, four for the largest) tell you which radius you're on.
NEMA 17 And NEMA 23 Panel Drilling Template
This 84 x 84 mm drill guide plate lets you drill stepper motor mounting holes in sheet metal, plywood or acrylic. It has 12 mm tall guide bushings for both patterns: a 31 mm square for NEMA 17 (3.4 mm holes for M3) and a 47.14 mm square for NEMA 23 (5.5 mm holes for M5). There is also a 3.4 mm centre hole for the hole-saw pilot, which you use to cut the 22 mm (or larger) boss opening. V-notches on the edges line up with scribed centre lines, so the motor ends up square and centred without measuring.
Pi 4 And Pi Zero Standoff Drilling Template
A drill-guide template for project boxes. It matches the 85 x 56 mm Raspberry Pi 4 board outline and has 8 mm-tall guide bushings on both the Pi 4 58 x 49 mm pattern and the Pi Zero 58 x 23 mm pattern, so standoff holes in a stock box without bosses line up the first time. The 2.9 mm bores take a 2.5–2.8 mm bit or a scribe. Open windows show the box floor underneath, and V-notches at the pattern centre let you line it up with marked centre lines.
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.
