Under-Desk Keyboard Tray Slide Rail
A print-in-place dovetail slide that turns any flat board into a pull-out under-desk keyboard or mouse tray — 175 mm rail, 99 mm of travel, 27.5 mm total drop below the desk. The rail screws to the desk underside through four 4.5 mm ears (fits #8 wood screws, 4.2 mm shank, or M4 machine screws) and the 60 mm carriage takes three M4 heat-set inserts on a 20 mm pitch so the tray board bolts on from below. Print two, one per side, spaced to suit your board.
Under-Desk Dock Clamp Mount
A 150 x 44 x 42 mm under-desk mount with a print-in-place sliding jaw that clamps a USB-C dock, hub, mini PC or laptop power brick up to 90 mm wide and 30 mm thick, so it hangs under the desktop instead of sitting on the floor. Screws to the desk underside with four #8/M4 wood screws through 4.5 mm holes; the captive dovetail jaw locks with an M4 set screw threaded into an M4 brass heat-set insert (5.5 mm bore, 7.6 mm deep), and 6 mm lips on both jaws hook under the device so it slides in from the side and cannot drop out.
Monitor Top Webcam Clamp Shelf
A clamp-on shelf that straddles the top bezel of a monitor and gives a webcam, action cam or small light a solid 41 mm deep platform with a 6.8 mm obround slot for a 1/4-20 tripod screw (14 mm of fore/aft travel) and a 3 mm anti-slide lip. The 18 mm wide throat swallows panels from about 5 mm to 18 mm thick and locks with an M4 x 25 screw into an M4 heat-set insert (5.5 mm bore) in the rear jaw, so nothing presses on the screen; two M3 clearance holes in the deck take a light arm or adapter plate. Overall 78 x 34 x 42 mm, printed as a single profile with no overhangs or supports.
Desk Edge 2020 Post Clamp
A C-clamp that grips a desktop 12–30 mm thick and holds a vertical 2020 extrusion post at the desk edge, so you can mount a lamp, mic boom, webcam or a small shelf without drilling the desk. 99 x 38 x 30 mm body with a 20.4 mm square socket 40 mm deep (two M5 clearance holes for T-nuts lock the post) and two M4 heat-set inserts in the lower jaw for the M4x30 clamp bolts; the flat 38 x 30 mm upper jaw pad bears on the desk surface and the rear face registers flush against the desk edge. Prints flat on the plate, no supports.
