Standing Desk Keypad Knee Bumper Bar
This U-shaped bar screws to the underside of a desk and hangs below a sit-stand desk's up/down keypad, so a knee or chair arm hits the bar before it can press the buttons and move the desk. It fits keypads up to 140 mm wide and 38 mm deep. The fingers still reach in from the front, and the 5.0 mm slotted holes in the two flanges take #8 or #10 wood screws with 8 mm of front-to-back adjustment. Overall size is 176 x 52 x 28 mm, and it prints flat so the knee load stays in the layer plane.
Under-Desk Cable Slack Reel
This reel screws under a desk or onto a desk leg and takes up extra monitor, USB-C or charger cable. You wrap the cable around a 50 mm hollow drum, which keeps it above a safe bend radius. A flared lip holds the wraps in place, and two 7 mm notches in the lip let the cable in and out. The base is 96 x 76 x 5 mm with four countersunk 4.5 mm holes for #8 wood screws or M4 bolts. There is 31 mm of wrap height, and the lip underside is 45°, so it prints without supports.
Under-Desk Charger Brick Strap Cradle
A 176 x 96 mm plate that screws to the underside of a desk with four 5.5 mm slots (fits #8, #10 or M5 pan-head screws). It holds a laptop charger brick up to 74 mm wide against vented 3 mm ribs, using a 25 mm hook-and-loop strap threaded through 27 x 4 mm slots. The 32 mm flared end horns take the spare cord, so the brick and its cable stay off the floor.
Under-Desk 1/2 in EMT Cable Rail Hanger
A pair of these screws to the underside of a desk with #8 wood screws (4.6 mm clearance holes, 48 mm apart). Together they hold a length of 1/2 in EMT conduit (17.9 mm OD) about 60 mm below the desktop as a hanging rail for power-strip cords, chargers and loose cables. The rod pushes sideways into a 16.9 mm snap mouth on an 18.3 mm saddle. The bracket is printed on its side, so the hanging load runs along the layers instead of across them. It also has gussets and a zip-tie slot for strapping a cord to the leg.
Under-Desk Swing-Out Pivot Tray
A 120 x 80 x 18 mm tray that hangs under a desk from a single pivot screw and swings out when you need your phone, keys or pens. A 22 mm tall corner boss holds the tray rim 4 mm below the desk. Its 5.5 mm bore takes an M5 bolt with a T-nut, or a #10 wood screw (4.8 mm shank) with a washer. The tray has a divider rib, a front finger scoop and a 10 mm charging-cable notch.
Desk-To-Wall Standoff Cable Trough
This part screws under the back edge of a desk with two #8 wood screws (4.2 mm shank, through 4.8 mm slots with 22 mm of travel). Its 6 mm-wide bumper keeps the desk about 40 mm off the wall, so the desk can't slide back, crush plugs or scuff the paint. Between the desk and the wall it forms a 28 x 23 mm cable trough with a 12 mm snap-in opening that runs the length of the desk.
Under-Desk Game Controller Hanger
A C-shaped hanger that screws to the underside of a desk. A 30 mm-wide, 55 mm-deep tongue fits between the grips of an Xbox- or PlayStation-style controller, and a 12 mm lip keeps the controller from sliding off. It mounts with two #8 (4.2 mm) pan-head wood screws through 4.5 mm holes. A 7 x 30 mm slot in the drop wall lets the charging cable run back under the desk, and the part prints on its side so the load runs along the layers.
1 in PVC Rocking Footrest End Stand
This is one end of an under-desk rocking footrest. Print two of them and join them with two lengths of 1 in schedule 40 PVC pipe (33.4 mm OD), which sit in 33.8 mm blind sockets 25 mm deep. You can fix each pipe with a #8 screw through the 4.5 mm cross holes or with PVC cement. The stand is 160 x 109 x 28 mm with an R260 rocker arc on the bottom and open windows to save plastic. It prints face-down, so foot load goes into the plate across the layers' strong direction instead of peeling them apart.
Under-Desk Gusseted Backpack Hook
A J-hook that screws up into the underside of a desk or table top with two #8 (4.2 mm) countersunk wood screws. It gets a backpack, laptop bag or purse off the floor. It has a 22 mm wide, 16 mm deep rounded throat for straps and a 45° gusset between the drop stem and the flange. The part is 60 x 68 x 24 mm and prints on its side, so the load from a hanging bag runs along the layers instead of across them.
Under-Desk Qi Charger Spring Bar
A stepped leaf-spring bar that screws to the underside of a desktop and presses a Qi wireless charging pad flat against the wood, so the desk surface becomes a charge spot — no double-sided tape. 156 x 24 x 14 mm; the sprung arms give a 10 mm nominal pad gap with about 3 mm of travel either way (pads roughly 7-14 mm thick, up to ~100 mm across), four 4.5 mm holes on a 136 x 12 mm rectangle take #8 wood screws (4.2 mm shank) or M4, and two 7 mm reliefs across the pressure face clear the pad's cable. Charging through the top needs a thin panel or a routed recess.
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 Laptop Hanger Bracket
A gusseted C-channel bracket that screws to the underside of a desk and holds a closed laptop horizontally by one edge — print two and slide the laptop in from the front. The channel has a 24 mm clear opening (fits any 14–24 mm closed laptop), a 26 mm deep shelf and a 14 mm top retaining lip with a tapered lead-in; the bracket is 78 x 42 x 32 mm and drops 42 mm below the desk. Four 10 x 5 mm slots in the 52 mm mounting flange take #8 wood screws (4.2 mm shank, 16–20 mm long) and give ±10 mm of lateral adjustment so you can set the spacing to your machine without re-drilling. The whole part is a single prism, so it prints flat on its side face with zero overhangs and the layer lines run across the bending load rather than along it.
Under-Desk Slide-Out Pen Drawer
A print-in-place hanging drawer that screws to the underside of a desktop with four M4 (or #8) wood screws on 4.5 mm clearance tabs, giving you a 74 x 104 x 19.6 mm two-compartment tray for pens, keys and USB sticks without eating desk surface. The tray hangs on 3 mm tongues captured in 45°-roofed grooves in the side rails, slides out 41 mm on a positive stop, and prints as one 116 x 118 x 26 mm assembly with 0.5 mm clearances — no supports, no assembly.
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.
Under-Desk Power Strip Cradle
A screw-up bracket that lifts a power strip (or a laptop brick) off the floor and onto the underside of a desk or bench: two 15° V-arms self-centre any body 38–52 mm wide, and a 4.8 mm zip tie cinches it down through four slots, its loop hidden in a 2.2 mm groove milled into the desk-facing side so the plate still sits flat. 68 x 32 mm footprint, 31 mm tall, two 4.5 mm counterbored holes on 26 mm centres for M4 or #8 screws. Print two and space them along the strip.

Under-Desk Cable Management Tray
A 145 x 60 x 28 mm screw-up tray that mounts to the underside of a desk to hold a power brick, surge strip and cable slack off the floor. Cables snap in through a 46.8 mm mouth under a 45° retaining lip, both ends are open for pass-through, three vented windows per side let cables exit anywhere, four zip-tie slots strap a brick down, and four raised pads take M4 (or #8) screws in 4.5 mm clearance bores with 8.4 mm counterbores so the heads sit flush below the cables.
