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.
Dual-Edge Bowl Scraper With Dough Ruler
This is a 120 x 95 mm bench and bowl scraper, 2.8 mm thick. One edge is straight and bevelled down to 1.2 mm for cutting and portioning dough. The opposite edge has a 65 mm radius curve for scraping mixing bowls clean. Grooves every 10 mm along the straight edge, with longer marks at 0 and ±50 mm, let you measure while you cut. A ribbed finger-grip slot stiffens the middle, and you can hang the scraper from it on a hook.
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.
Desk-Side Screw-On Pen And Scissors Caddy
A caddy that screws to the side of a desk, pedestal or monitor shelf and keeps pens, scissors and a ruler within reach without using any desk space. It measures 124 x 25 x 42 mm and has two 13 mm pen wells, a 24 x 9 mm scissor-blade slot and a 34 x 4 mm ruler slot. Two side ears take #8 wood screws or M4 bolts through 4.6 mm holes.
Bolt Length Scale Lane Tray
A 150 x 104 x 24 mm fastener tray with five bolt bins, each paired with its own 27 x 18 mm nut pocket. Along the front runs a 90° V-groove with a head-stop at one end and a molded-in scale: mm ticks every 5 mm on one lip (0–140 mm) and inch ticks every 1/4 in on the other (0–5.5 in). Drop a bolt into the groove with its head against the stop, read the length, then put it in the right lane.
