Split-Span Laser Gantry
Created today
Description
A modular laser mounting gantry spanning an exact 330mm width. Built for smaller print beds, the two-piece frame locks together in the centre with a clearance-tuned puzzle joint that draws the span tight when seated.
Adjustments & Tolerances
- The Joint: 0.5mm clearance around the jigsaw neck. Best printed flat to put layer strength along the span.
- The Slider: Sits exactly over the seam and locks down with an M4 tap bolt through the top.
- Laser Mount: Single 6.5mm hole on the face block, ready for standard laser unit clamps.
- Table Mount: Four 5.5mm mounting holes positioned straight down through the feet for screwing straight into your baseboard.

Hoof Evener Thumb Ring
A low-profile thumb ring designed to friction-fit onto the center support of a hoof-evener ruler. The ring is split to flex over a variety of thumb sizes while keeping the geometric center locked perfectly inline with the measurement zero-point. Remix Hooks Thumb clearance: Currently set to an inner diameter of 22mm. The 5mm split opening allows for expansion, but the base diameter is the first thing to dial in for a specific hand. Strut channel: The rear mounting slot is sized for a 12.5mm × 4.5mm vertical support. Adjust this block to match the actual sheet metal or printed strut of the evener. Locking hole: A 3.3mm pilot hole runs through the back wall. Drive an M4 set screw or short bolt through it if the friction fit over the strut needs extra bite.
Truss-Web Parallel Clamp Arm
Industrial structural bridge for mounting a 4040 V-slot extrusion parallel to a standard 40mm round pipe. This design strips away unnecessary bulk while maintaining high structural rigidity through an internal cross-braced truss. The main arm carries dual clamping faces, mating with custom outer caps that secure via standard M5 hardware. Dual-Clamp System: Full wrap-around clamps for both the 40mm pipe and the 40x40 extrusion. Tension Gaps: 1mm built-in clearance on the clamping faces ensures the bolts can bite down properly without the halves bottoming out. Weight Reduction: Large through-holes cut into the web remove non-structural mass and reduce print time, leaving an I-beam-like internal structure. Hardware: Uses standard M5 bolts. The main arm includes integrated hex catches for standard M5 nuts, while the outer caps feature counterbores for the bolt heads.
montre
What it's for A 3D-printable watch case modelled on dive-watch proportions. Features a scalloped rotating-style bezel with minute markers, a fine threaded base for the case back, and integrated lugs for a standard watch strap. The inner cavity tapers to secure a movement, with a lip cut for a domed crystal. Dimensions Overall Case: 42 mm diameter Inner Cavity: 41 mm base, tapering to 40.4 mm at the dial Lugs: Spaced for a 20 mm strap Crystal Seat: 41.4 mm diameter, 1 mm deep Stem Hole: 1.1 mm diameter at the 3 o'clock position Threads: 0.5 mm pitch, matching case back included Print notes The case back uses a very fine 0.5 mm thread pitch. This requires a well-calibrated printer and low layer heights (0.12 mm or finer) to print cleanly. You may need to scale the case back slightly on the X and Y axes depending on your printer's tolerances.
Anello Frazionato da Palo
Un anello di spessoramento diviso a metà, progettato per essere montato attorno a un palo da 137 mm di diametro. Profilo: Parete spessa 3 cm Fori: Quattro fori passanti verticali, diametro 4 mm, disposti in quadrato con lato 121 mm Assemblaggio: Spaccato centralmente per consentire l'installazione su tubi e pali esistenti senza doverli sfilare. Utile per creare spessori o basi su tubolari in metallo o PVC.
Screwdriver Handle With Bit Storage
Digging through a loose pile for the exact bit wastes time, so this 1/4-inch hex screwdriver handle keeps six spare bits loaded directly in the base. The main driving socket holds the active bit with a recessed magnet, while the spare slots are kept out of the way so the sharp ends stay clear of your grip while turning. Fit and Hardware Overall Size: 100 mm long by 30 mm diameter. Main Socket: 1/4-inch (6.35 mm) hex, sized to 6.6 mm for printed clearance, with a pocket at the bottom for a standard 6x3 mm neodymium magnet. Spare Magazine: Six hex slots cut 18 mm deep, leaving roughly 7 mm of a standard 1-inch bit exposed so they can be pulled out by hand. Grip: Six flutes offset from the bit holes to maintain wall thickness and provide torque.
Wide Stance Filament Spool Stand
Filament spools that hang off the edge of undersized holders are a constant source of drag and jams. This A-frame stand widens the track, catching oversized spools before they can derail. Fit and Bed Limits Inner Clearance: 160 mm between the uprights Base Width: 180 mm Spindle Height: 192 mm Printability: The entire layout is spaced to fit on a 220x220 mm bed without needing rotation or supports.
