It features a heavy-duty front panel with recessed text, horizontal ventilation slots for internal environmental sensors (like the BME680 and gas sensors), and a heavily shrouded SOS button to prevent accidental triggers while keeping it accessible in an emergency. The housing is secured entirely from the rear, ensuring a tamper-resistant front face. Dimensions Overall Size: 75 mm × 125 mm × 35 mm (including rear strap loops). Internal Capacity: 69 mm × 119 mm × 22 mm, providing ample room for an ESP32, LoRa modules, sensors, and a lithium battery. Mounting Interface: Rear panel features 38 mm wide integrated strap loops for chest or harness mounting. Fasteners: Requires four M3 countersunk screws for the rear panel, and standard M2/M2.5 self-tapping screws for internal standoffs. Assembly Print the front shell face-up (or face-down with supports for the button shroud), and the back plate with the strap loops flat against the bed. The SOS button is modelled as a separate piece to allow printing in an emergency red or high-visibility filament before dropping it into the front panel assembly.
Supervisor Electronics Shell
Generic hobby boxes crack at the screw posts the second time you open them, and their exposed hardware snags on everything in a bag. This is a clean, rugged shell that closes tight without external fasteners and keeps the wiring where it belongs. The front panel traps the alert button from the inside, so it can't be ripped out or jammed sideways. Internal Specs Dimensions: 120 × 75 × 35 mm external. Walls: 3 mm solid shell. Standoffs: Four integrated posts (2.5 mm bore) spaced for a standard ESP32 footprint. Clearance: 0.25 mm tolerance on the friction-fit lid lip. Print flat, no supports required.

Modulær Vandmodstands-Blok
Et modulært testsystem til at måle vandmodstand ("bluff body"-træk). Hovedskroget fungerer som en tung ballastkasse med master i bunden, der lader dig justere vægten ved at placere standard fysiklodder. Udskiftelige frontplader gør det nemt at isolere formfaktorens betydning for modstanden. Dette design er tænkt som et udgangspunkt for at teste forskellige stævnprofiler: Modulær front: Svalehalesporet lader dig nemt slibe eller designe nye frontprofiler uden at skulle printe hele skroget igen. Justerbar dybgang: Masterne (3.9 mm i diameter, 20 mm afstand) er lavet specielt til standardlodder — tilføj eller fjern lodder for at ændre tyngdepunktet. Trækpunkter: Øjerne er placeret 10 mm fra toppen, så din snor kører lige ved vandlinjen i et fyldt kar.

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.

10mm Bore Mod 2 Gear
Standard Mod 2 spur gear, cut with 20 teeth and a straight 10 mm center bore. Designed for 20 mm face-width mesh engagements. Check your shaft diameter before sending this to the plate. If it is going onto a nominal 10 mm steel shaft, a dead 10 mm printed bore will bind on press-fit; you will need to ream it or step the bore up to 10.3 mm to get a slip fit. Standard: Module 2 (Mod 2) Face Width: 20 mm Tooth Count: 20 Center Bore: 10.0 mm (straight, no keyway) Pitch Diameter: 40.0 mm Outer Diameter: 44.0 mm
Bluff-Body Trækskrog
Et rektangulært fartøj designet til at skubbe en mur af vand foran sig og maksimere vandmodstanden ved lave hastigheder. Det simple kasse-skrog fjerner laminart flow fra forsøget, mens det centrerede ballast-tårn sikrer, at dybgangen forbliver helt vandret under målingerne. Centreret ballast: Tappen er placeret i skrogets geometriske midte og passer til standard fysiklodder (6 mm hul), så båden ligger fladt i vandet. Eksterne trækøjer: Fritstående for- og bagøjer giver god plads til både kraftmålerens krog og en stabiliserende agter-line. Bluff-body profil: Den flade stævn tvinger vandet til at bryde skarpt omkring skroget, hvilket øger drag-koefficienten markant.
Wide-Stance Filament Bracket Set
A sturdy, flat-packed filament spool holder with an open frame base and dual arching uprights. Designed for standard 16mm rods or dowels, this is laid out flat for maximum printing strength along the layer lines.
