20mm Threaded Collet Clamp
Created 9 days ago
Remixed 2 times
Description
A heavy-duty threaded collet clamp scaled up to grip 20mm round stock. The two-part design features a slitted threaded body and a matching nut that compresses the taper to lock onto the rod.
Sizing and adjustments
- Bore: 20.2mm (clears a 20mm rod smoothly before compression)
- Threads: M30 with a coarse 2.5mm pitch to survive FDM printing
- Wrench flats: 40mm hex on the body, 42mm on the nut
Both parts print flat on their bases without supports. If the grip is too tight or loose depending on your printer's flow, scaling the nut by 1-2% on the X/Y axes will dial in the friction.

20mm V-Notch Bench Dog
A drop-in clamping block designed to secure round stock on a workbench equipped with 20mm dog holes. The top face features a continuous 90-degree V-notch that cradles dowels, pipes, and tubular frames, preventing rotation or slipping during sanding, routing, or assembly. Compatible with standard 20mm workbench dog holes Peg diameter is modeled at 19.6mm to ensure smooth insertion and removal without binding Main clamping block measures 50x50x40mm 30mm peg length resists racking under side-load clamping pressure
Compact Hex Key Pouch
A compact, low-profile pouch for a standard set of seven metric Allen keys (2 mm through 8 mm). Designed for belt or pocket carry, the main body is slimmed down and heavily rounded to prevent it from catching on clothing or digging in while working. The holes run completely through the block so sawdust and metal shavings cannot collect inside. What it's for Keeps your hex keys organized and immediately accessible on a belt or work apron. The integrated spring clip features a tightly radiused catch designed to grip fabric securely without feeling bulky. Dimensions Overall footprint: 68 × 16 mm (body), plus 6.5 mm depth for the clip. Height: 50 mm. Hole diameters: 8.5, 6.5, 5.5, 4.5, 3.5, 3.0, and 2.5 mm, providing a comfortable 0.5 mm clearance for each key. Print notes Print upright as oriented (the flat base on the bed). The through-holes require no supports, and the integrated clip relies on the Z-axis layer strength — PETG or ABS is highly recommended for the flex and durability of the clip, though PLA works for lighter duty.
Acoustic Harmonica Silencer Enclosure
A custom-designed acoustic enclosure built to fit a standard 10-hole diatonic harmonica (specifically dimensioned for the Fender Blues Deluxe). This silencer is built to drop external volume during practice while preserving a totally natural playing feel. The enclosure features a wide front opening that allows direct lip contact with the harmonica body, avoiding any forced embouchure changes. The rear of the enclosure acts as a miniature acoustic labyrinth, forcing outgoing air through staggered baffles and multi-chamber pathways to break up sound waves before they exit the exhaust ports. Remixing and Assembly Clearances: The default harmonica cavity includes a 0.4mm clearance, with 4mm of allocated depth at the rear for installing your own acoustic foam. Two-Piece Shell: The model splits into a top and bottom shell, joined by integrated friction-fit alignment pins. Print Settings: Prints completely support-free when the large flat mating surfaces are placed face-down on the build plate. PLA or PETG recommended for rigidity and snap-fit durability.
Inline Screw Driver Retainers
These four independent sleeves snap over the shaft of a screwdriver (or hex bit) and grip the screw from the sides, making overhead installation much safer. The driver bit drops straight through the open top to engage the screw head directly. As the screw bites into the material, the flexible jaws slide back up the driver shaft, releasing the screw automatically without jamming against the ceiling. What it's for Holding screws securely to a driver for overhead work Accommodates four size ranges (1–8 mm screw diameters) Slides freely on the driver shaft as the screw drives home Dimensions Tiny: Fits 1–2.5 mm screws (red) Small: Fits 2.5–4 mm screws (yellow) Standard: Fits 4–6 mm screws (green) Large: Fits 6–8 mm screws (blue) Wall thickness tapers down to ~1.5 mm at the jaws for optimal FDM flexibility. Print notes Print them standing vertically (as oriented) so the layer lines follow the curve of the C-clip. This ensures maximum lateral flexibility when snapping screws in from the side. No supports required.
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.
