OptiFix — CD Diffraction Rig
Created today
Description
OptiFix is a one-piece rigid alignment jig designed for CD diffraction experiments. It firmly holds a standard 120 mm CD in a vertical slot and aligns a 14 mm laser pointer on an exact perpendicular axis, ensuring a clean horizontal diffraction pattern.
Features
- Absolute Alignment: Positions the laser center precisely 65 mm above the base, directly in line with the CD's center.
- Track Targeting: The laser axis is offset sideways to hit the data tracks 2.3 mm inward from the CD's outer edge, catching the vertical track lines to cast a horizontal pattern.
- Snap-in Towers: Two separate cradle towers grip the 14 mm laser via a narrow 12.5 mm top opening, eliminating the need for rubber bands.
- Stable Base: An expanded L-shaped footprint keeps the setup planted on the desk.

8mm Ruled Cookbook Stencil Rig
A full-bed 3D-printable stencil rig engineered specifically for 8mm ruled notebooks. Designed around a 75x142mm central master frame that aligns directly to the paper's ruling. Fitment and Clearances Mating Surface: Any standard 8mm ruled notebook page. Frame Dimensions: 75mm wide by 142mm tall, housing 16 guide slots. Tiles Included: 168 modular stencil inserts (6.1mm tall), spanning measurements, spices, meats, and techniques. Clearance: Tiles are intentionally sized 0.2mm smaller than the frame slots to ensure they drop in clean without binding. Ensure your printer's first layer isn't squashed, or you'll lose that margin. Bed Requirement: The entire 169-piece layout measures roughly 215x216mm. It is tightly packed to max out a standard 220x220mm Ender 3 print bed. Skirt lines must be kept minimal or disabled. Tooling: Use a fine-liner or 0.3mm technical pen; standard ballpoint collars will jam in the stencil voids.
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.
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.
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.
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.
