20° Writing Slant Board Side Bracket
This bracket turns any 6 mm or 1/4 in (6.35 mm) plywood or hardboard panel into a 20° writing and drafting slant board. The board edge slides in from the back along a 6.8 mm groove and stops against a closed front end, and a 4 mm lip keeps the board from lifting out. Print two and mirror one in the slicer. Each bracket is 160 mm long, 16 mm thick, 14 mm tall at the front and 72 mm tall at the back. It prints flat with no supports, so the weight of your hands loads the walls along the layer lines.
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.
8 mm Rod Rolling Parallel Ruler
This 150 mm drafting ruler rolls on a 142 mm piece of 8 mm smooth rod captured inside it, so you can draw evenly spaced parallel lines and hatching without a T-square or drafting board. The rod turns in an 8.3 mm slip-fit tunnel and sticks out about 0.6 mm through a bottom slot. An M3x10 self-tapping screw stops the rod sliding out of the open end. The ruler has bevelled drawing edges on both sides and 10 mm tick notches along one edge.
30/60 Drafting Set Square With Ink Edge
A 30/60/90 drafting set square, 138.6 x 80 mm on the legs with a 160 mm hypotenuse and 3 mm thick. It has a 45° undercut inking edge so pen ink doesn't wick under it, 5 mm tick grooves along both legs, a row of 3/4/5/6/8/10 mm circle-template holes, and a centre lift-out window. Use it for sketching layouts, wiring diagrams and project plans on the desk.
150 mm Grooved Drafting Protractor
This is a 150 mm half-circle drafting protractor, 3.2 mm thick. Angle ticks are cut into the top every 5°, with longer ticks every 10° and the longest at 0/45/90/135/180°. It also has a 140 mm ruler along the base and an M3 clearance hole (3.4 mm) at the vertex, so you can mark the centre point or pin it down with an M3 screw and swing it. Two open windows let you see the drawing underneath, and the whole part uses about 20 cm³ of plastic.
