Turret-Profile Sharpie Plotter Chuck
Created today
Description
A stepped, turret-profile chuck designed to adapt standard Sharpie markers for use in pen plotters expecting an 11mm tool. The lower section drops seamlessly into the machine's carriage, while the flared upper collar houses an 11.5mm bore tailored to the 11.3mm grip and 13mm shoulder of a standard marker.
Design Details
- Compression Collar: A vertical flex slot allows the upper section to clamp firmly onto the pen body without warping the base.
- Zip-Tie Channel: A recessed groove in the collar provides a secure seat for a standard zip tie to cinch the mechanism closed.
- Internal Stop: An internal taper arrests the pen's shoulder, keeping the tip height consistent across tool changes.
- Tip Clearance: An 8.5mm lower bore ensures the marker tip passes through smoothly without clipping the adapter walls.

Channel — Micro U-Profile
A precision micro U-channel profile built to exact specifications. Designed as an inverted U-shape, it features consistent 2mm wall thickness throughout. Dimensions Width: 8 mm Total Depth: 6.5 mm (yielding a 2.5 mm internal channel) Total Height: 9.5 mm Wall Thickness: 2 mm on both verticals and the top span Print notes Prints easily in its current orientation with no supports required. A slight 0.2mm chamfer has been applied to the outer top edges to eliminate sharp corners.
Narrow Dyson V11 Crevice Tool
A specialized extension nozzle designed for reaching deep into narrow spaces, such as car seat gaps and tight tracks. The base features a 35.5mm inner diameter sleeve tailored to fit over a 35mm Dyson V11 wand collar, providing a secure friction fit over a 25mm depth to clear standard spring-clip catches. The main body flattens out, while the final 20mm tapers sharply into a thin slot for maximum penetration into cramped areas. Mounting interface: 35.5mm ID, 25mm deep sleeve intended for Dyson V11 mounts. Nozzle profile: Flattens along the shaft, tapering to a highly restricted slot at the tip. Target application: Automotive interior detailing and reaching confined household crevices.
OsteoHinge — Resettable Femur Simulator
This anatomical simulation bone is designed for realistic mechanical training and demonstrations. Modelled at a compact 200mm footprint to suit standard print beds, it features a functional, re-settable fracture mechanism built straight into the main shaft. The midshaft utilises an interlocking V-notch joint tailored for sudden directional failures. By threading elastic shock cord through the central internal channel and tying it off in the polar counterbores, the bone is tensioned. It rests firmly aligned and rigid until lateral force (a "push") hits the threshold, causing the V-notch to ramp open and cleanly hinge to simulate a fracture. Stopping the lateral pressure causes the elastic cord to snap the halves immediately back into the unmarred state. Assembly notes Hardware: Requires one length of 3-4mm elastic shock cord. Tie-down: Feed cord completely through the continuous central bore, stretch for the desired breaking tension, and secure via simple knots. Both ends feature counterbores specifically to hide the tie-offs. Scaling: Feel free to scale the assembly up uniformly to simulate a full adult male femur (~225%), but note you will require a correspondingly wider elastic band.
Brutalist Framing Outer Clamp
A monolithic, brutalist-inspired L-block designed to enforce exact ninety-degree angles on unruly lumber. Engineered specifically to cure the dreaded parallelogram effect in picture framing, this outer squaring jig cradles two boards firmly against its orthogonal walls while the glue sets. Design Notes: Oversized Clamp Cutouts: Generous 44mm slots on each arm easily accommodate standard bar clamps. Glue Relief Vertex: A central circular cutout ensures escaping squeeze-out never fuses the project to the jig. Rigging Anchor: A central tie-down hole offers a secondary strap point for complicated assemblies.
50mm Rounded 4-Hole L-Bracket
A custom L-bracket with a fully radiused profile at the end of each arm. Built to support structural corners, shelves, or custom frames. Arm Dimensions: 50mm length, 20mm width Thickness: 4mm Mounting: Four 5mm holes total (two per leg), spaced for alignment and balanced load distribution. Profile: Radiused ends to prevent snagging and improve visual clearance.
Piano Key Drill Index
Sweeping upward in a measured crescendo, this curved bit index arranges thirteen metric drill bits in an escalating semi-circle. Taking its silhouette from the staggered keys of a piano or the tiered architecture of a classical amphitheatre, the stepped block keeps each bit distinctly visible and accessible, transforming a standard workshop necessity into a sculptural display. Design Harmonics Measured progression: Accommodates thirteen metric sizes from 1.0mm to 7.0mm in 0.5mm increments. Clearance envelope: Each vertical shaft is oversized by 0.3mm, allowing bits to seat smoothly without rattling. Quick reference: Crisp, embossed numerical markings sit at the base of every tier for instant identification. The sweeping curve naturally fans the fluted steel outward, providing ample finger clearance when reaching for even the smallest diameters.
