BenchWeigh — Micro Scale Chassis
Created 12 days ago
Description
A straightforward two-piece chassis designed to house a standard 75mm 1kg load cell, an HX711 amplifier, and an ESP32 dev board.
The base unit includes a raised 6mm pedestal to secure the fixed end of the load cell, giving it the clearance it needs to deflect. A walled rear compartment keeps the amplifier and microcontroller contained, with a side cutout for routing cables to the load cell. The weighing platform is printed alongside it; it features a matching pedestal for the floating end of the load cell.
Dimensions
- Base Footprint: 120mm × 80mm
- Weighing Platform: 100mm × 80mm
- Load Cell Pedestals: 25mm × 16mm × 6mm
- Electronics Bay: 105mm × 35mm (internal)
Print notes
Both parts print flat on the bed. The screw holes are spaced at 15mm for standard M4 bolts and include 3mm counterbores on the print surfaces so the screw heads sit flush when assembled. The platform flips over to mount onto the floating end of the load cell.

SMARTBELT Line Monitor
Conveyor belts don't ask before they drift, and a shredded belt stops the whole line. This is a watchdog that mounts rigidly to a steel frame and actually looks at the belt. It features an adjustable heavy-duty C-clamp, a rigid enclosure for an ESP32, a telescoping sensor boom that spans the belt width, and a drop-down arm for proximity speed sensing. The modular design lets you swap out the laser inspection head or IR edge sensors without unbolting the main unit. Assembly & Installation Clearances: Mating faces on the boom base and telescoping arm include a 0.4mm tolerance to ensure a sliding fit straight off the plate. Hardware: Designed for M4 socket head screws on the front cover and M8 bolts for the main structural clamp. Material: Print in PETG or ASA for impact resistance and thermal stability. Support Strategy: The C-clamp and enclosure bodies print upright without supports; the sensor arms require minimal bridging support under the drop-down elements.
small Bottle Syringe Clip
A custom-sized double ring designed to couple a 14.5 mm syringe to a 31 mm bottle neck. Syringe bore: 14.5 mm with an 8 mm front insertion slot Bottle bore: 31 mm (snaps on via a 22 mm back slot) Clearance: 4 mm bridge spacing The branding is now recessed 0.6 mm directly into the bottle ring's inner wall, keeping the outer profile completely flush. Check your syringe outer barrel measurement before running this.
Biofloc Monitor Station Enclosure
An enclosure is only as good as the snarl of wires it prevents. This is a heavy-duty two-part monitor housing built specifically for FDM printing, designed to group, separate, and anchor a complete suite of biofloc water-quality electronics without turning into a bird's nest inside. The layout isolates the battery compartment at the bottom and keeps the DC buck converters and relay in a ventilated top section, leaving the central deck clear for the ESP32 and an array of sensor interfaces. Internal divider walls double as cable routing channels, forcing the wiring to stay orderly. Core Features Printability: Both halves print completely flat on the build plate (Z=0). The integrated bottom handle is flush with the front face to avoid overhangs. Dimensions: 170 mm width × 250 mm height × 75 mm depth. Hardware Required: 6× M3 screws for the rear cover; additional M3 hardware for the internal standoffs and the 16x2 LCD faceplate mount. Ports: Bottom panel holds 4× sensor ports (3× 8mm, 1× 6mm) with engraved labels. Right panel holds cutouts for 12V DC, an SD card slot, a rocker switch, and USB programming access.
Hilti Nuron Battery Mount
A wall-mounted receiver bracket for Hilti Nuron batteries. Heavy battery packs love to lever short brackets right out of the drywall. This bracket gives them a solid vertical footprint to spread that load, catching the battery's sliding interface on an internal U-channel with a dead stop at the base. Internal Channel: 63mm wide (48mm opening) Clearance: Counter-sunk screw holes keep the hardware below the sliding surface Detail: Features a debossed HILTI logo on the backplate that stays clear of the sliding path
28mm — Tapered Syringe Adapter
A specialized dual-ring tool designed to connect a small tapered syringe (5–6 mm) to a 28 mm bottle neck. Features Bottle Bore: 28 mm with a straight 8 mm snap-on cutout, finished with rounded entry tips. Syringe Bore: Tapered from 5 mm at the bottom to 6 mm at the top, ensuring a snug fit. Bridge: A short 6 mm tapered solid bridge connecting the two mounts smoothly. Branding: "SE Tool" engraved directly onto both side flanks of the tapered bridge.
LockDrop — Packout Cup Holder
A rugged, drop-in cup holder designed to integrate perfectly with the Packout system. Secures easily onto any standard Packout lid using an integrated twist-lock cleat that sits flush for straightforward 3D printing. The main body accommodates standard tumblers and bottles while the heavy-duty walls and gussets ensure side-load stability. Features Twist-Lock Cleat: Drops into standard female Packout receivers with a friction fit. Flush Base Construction: Designed to print cleanly without complex supports for the bottom locking mechanism. Heavy-Duty Walls: Thickened sides with structural gussets engineered for shop environments. Front Branding: Embossed Milwaukee logo wrapping the front curve for a finished tool aesthetic. Drainage: Integrated center channel prevents liquid and debris buildup.
