Square Tube Corner Zip-Tie V-Saddle Mount
This 50 x 44 x 34 mm saddle has a 90° V-notch that seats on the outside corner of any square tube or angle-iron leg from about 20 to 50 mm, including gate frames, shelving uprights and trailer rails. It also works on round pipe. Two tunnels sized for ties up to 5.5 mm wide pull it tight against the corner. The flat back face has two M4 heat-set insert bores 20 mm apart, so you can bolt on a light, sign, hook or sensor without drilling the tube.
Arduino Uno Keyhole Bumper Tray
A screw-down tray for the Arduino Uno R3/R4 footprint (68.6 x 53.3 mm board) with four 7 mm standoffs on the factory hole pattern, 2.6 mm self-tap bores for M3 screws, a 12 mm bumper rim on three sides and the USB/jack end left open. Two #8 keyholes 30 mm apart hang it on a wall or screw it flat, and a 19 mm cable-tie apron with four 3.5 mm slots strain-relieves the USB and barrel cords.
Pi 4 Under-Shelf Drop Hanger
This bracket hangs a Raspberry Pi 4B/3B+ upright under a shelf or desk. Two slotted holes take #8 wood screws (4.2 mm shank) and give 5 mm of side-to-side adjustment. The board sits on 6 mm standoffs with M2.5 clearance holes on the 58 x 49 mm pattern, and three gussets brace the 94 x 75 mm plate against the 32 mm screw flange. The bracket also has a vent window and two zip-tie slots for the cables, and the USB and Ethernet end stays open.
Pi Zero Four-Blade Cluster Rack
A vertical rack that holds four Raspberry Pi Zero boards 24 mm apart on printed fins. Each fin has diamond standoffs on the Zero's 58 x 23 mm hole pattern with 2.9 mm M2.5 clearance holes. Open slots in the floor and diamond windows in the fins let air rise between the boards. The side rails are kept low so the SD slots stay reachable, and four 4.5 mm holes take M4 or #8 screws for a wall or bench mount. The whole rack is 84 x 100 x 42 mm.
Flagged: a sharp edge or blade. Not for safety-critical use without independent engineering review.
SG90 Tilt Servo Tower
An upright tower that holds an SG90 micro servo on its side as the tilt axis of a pan-tilt head. It has a 23 x 12.6 mm through-window for the servo body, slotted tab holes so the tab screws still fit if the spacing varies a little, and a 44 mm tall wall braced by two gussets. The foot has three M3 clearance holes (3.4 mm) for bolting it to a pan plate or chassis deck.
2020 Swivel Pi 4 Panel Mount
This print-in-place swivel mount clamps to the side of a 2020 extrusion with two M5 T-nuts. It carries a 71 x 70 mm board plate that swings about 120° on a captive 8 mm pin, and an M3 screw pressing on the pin locks the angle. The plate has the Raspberry Pi 4 hole pattern (58 x 49 mm, 2.9 mm holes for M2.5 standoffs), so you can angle a Pi, display or driver board on a robot frame without designing a new bracket.
Slotted LiDAR Puck Riser Mount
A 112 mm adapter deck that bolts a hobby 2D LiDAR puck (RPLIDAR A1/A2, LD06/LD19 class) to a rover chassis: eight radial 3.6 mm slots accept any 2-, 4- or 8-screw pattern on a 34–64 mm bolt circle, so one plate fits whatever puck you bought. Four integral 18 mm posts raise the scan plane above the deck and land on a 90 mm cross pattern of 3.4 mm M3 clearance holes (at ±45 mm on X and Y); a 26 mm centre bore drops the USB/UART pigtail through, with a pair of zip-tie slots for strain relief. Prints plate-down with no overhangs and flips over to install — use M3 x 25–30 screws down through the ears into the deck.
Hole-Free PCB Edge Clamp Carrier
A 92 x 54 mm carrier plate that mounts bare PCBs with no mounting holes — the fixed rail and a print-in-place dovetail jaw grip the board edges with 1.2 mm retaining lips, covering board widths from 11 to 65 mm of standard 1.6 mm FR4. The jaw locks with an M3 screw into a heat-set insert (4.0 mm bore) that jacks the dovetail tight, and the plate has four M3 clearance holes plus two zip-tie slots for cable strain relief.
Bayonet Twist-Lock Quick-Change Mount
A two-piece bayonet coupler that prints as one captive assembly: drop-in plug, twist 60° and three keys lock under the socket lip, past a detent bump and into a hard stop. Socket flange is 68 mm square with M4 clearance holes on a 56 mm square (14 mm tall); the 40 mm plug disc takes M4 on a 22 mm square, with a 20 mm centre pass-through for cable or a shaft — for swapping lights, sensor pods, cameras or tool heads off a fixed base.
LED Strip Corner Channel Mount
A 90° corner channel for 10 mm wide LED strip (5050/2835/COB) that snaps the strip in under retaining lips and hides the soldered corner joint in a recessed 21.6 mm chamber with a side notch for the feed wires. Footprint 65 x 65 x 8 mm, 10.6 mm channel with a 9.4 mm snap opening, four counterbored M3 screw holes so the heads sit flush below the strip.
NEMA 17 AS5600 Encoder Mount
A closed-loop encoder tower that bolts to the rear face of a NEMA 17 stepper (42.3 mm plate, 31 mm M3 pattern, 24 mm boss clearance) and holds an AS5600 magnetic encoder board 26 mm above the faceplate — right over a 6 mm diametric magnet glued to a standard 24 mm shaft. The deck carries eight 2.9 mm M2.5 holes on 19 mm and 29 mm square patterns so most breakout boards land centred, with a 12 mm sensor window and 12 mm side openings for the cable and a hex key.
Video Doorbell 30 Degree Wedge
A 30° horizontal-aim wedge that sits between a video doorbell or small security camera and the wall, swinging the field of view across an offset walkway or corner entry — 46 mm wide, 84 mm tall, tapering from 5.2 mm to 31.8 mm deep. Six 4.5 mm through-holes on the centreline (M4 or #6 screws) give nine bracket spacings from 28 to 68 mm, a 26 x 16 mm pass-through carries the bell wires, and the hollow shell is symmetric so flipping it end-for-end aims the other direction.
Handlebar Accessory Extender Bar Clamp
A split clamp for a 31.8 mm handlebar that carries a second 22.2 mm accessory bar stub 55 mm out to the side, so lights, a GPS, a bell and a phone mount stop fighting for stem space. Closed by two M5 bolts with captured nuts, 99 x 44 x 55 mm, gusseted web under the stub.
