Spool Hub for 8mm Rod
Created 12 days ago
Description
Half-width spool adapters let a heavy 1kg reel tilt, bind, and ultimately drag on the mounting rod until the extruder starts clicking. This hub fixes the wobble by spanning the entire inner width of a standard spool, keeping it tracking square. The flange includes four oversized cutouts so you can check how much filament is left without pulling the whole assembly off the rack.
Fit Dimensions
- Spool bore fit: 52.5mm outer diameter (slip fit for standard 53mm spools).
- Rod fit: 8.5mm center bore (clearance for 8mm rods).
- Insertion depth: 65mm body, capped by a 3mm flange.

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.
Flanged Triangular Drop Box
Drop-in triangular trays always slip through the hole they're meant to sit in. This is a heavy-duty triangular insert with a massive flange, designed to drop exactly 100mm into a cutout and stop dead on the rim. Dimensions Main Triangle: 150mm on all sides Drop Depth: 100mm total Flange Overhang: 30mm outward lip Wall Thickness: 5mm (strong enough for tools or heavy parts)
