90° Bevel Gearbox Assembly
A fully functional 90-degree bevel gearbox with 5 mm hex bores on both the input and output gears. The split housing prints without supports and clamps the gear stack together when the face flanges are bolted down. Specifications Transmission: 1:1 ratio bevel gears (16 teeth, 90-degree mesh). Input/Output: 5 mm hex bores on both gears, measuring 5.2 mm across the flats including 0.2 mm printing clearance. Housing: Split base and top, each 45 × 45 × 20 mm, designed to print flat without supports. Mounting Interfaces: Four 4.3 mm clearance holes on each face flange, arranged in a 25 mm square pattern. Assembly: The housing halves are clamped together when bolted to a surface using the face flanges; an extra M3 hole in the rear corner provides optional tightening. Printing: All pieces print flat without supports; the housing and gears assemble after printing.
Module pour rail 17,76 mm avec passage de fils
Ce module réunit une base à glissière et un corps supérieur plein et fermé. La base se glisse par l'extrémité d'un rail de 17,76 mm sans vis : deux lèvres à 45° s'engagent dans le col du rail. L'écart entre les lèvres est de 17,76 mm, avec un jeu d'environ 0,2 mm sur la largeur du dessus du rail (21,17 mm). Elle est dimensionnée pour un col de 17,76 mm ; sur un col de 16 mm, elle serait lâche. Le corps supérieur fait 50 mm de long. Une seule extrémité conserve une collerette de Ø28 mm sur 3,5 mm d'épaisseur, avec un contour en relief de 2,24 mm de large sur sa face extérieure : le centre est creusé de 1,5 mm et l'arête extérieure est arrondie à 1 mm, ce qui laisse environ 2 mm de matière au fond du creux. Entre cette collerette et l'autre bout, le corps est aplati et plein, large de 28 mm, avec le dessus arrondi et une pente inclinée qui passe d'environ 11 mm de haut près de la collerette à environ 6,9 mm à l'extrémité basse. Un canal de Ø6 mm traverse toute la longueur pour le passage des fils ; il reste droit et dispose d'environ 2,5 mm de matière au-dessus de la base. À l'extrémité basse, le haut du canal affleure la surface et s'ouvre sur quelques millimètres, dans la zone de la fente. Une fente de 4 mm de large relie ce canal au-dessus de la partie plate ; dans le sens de la longueur, une rampe de même largeur guide les fils depuis le bout bas vers le centre de la pièce et s'arrête à environ 3,5 mm du bout plat, avec une pente d'environ 71°. Le corps ne comporte pas d'alésage central pour un module laser, seulement ce canal et cette fente. Un renfort concave de rayon 4 mm relie la face intérieure de la collerette au-dessus de la partie plate, sans dépasser le Ø28. Il s'étend sur environ 4 mm le long du tube, mesure 20 mm de large, n'atteint pas les côtés de la partie plate et ses arêtes latérales sont arrondies à 6 mm. Les deux coins verticaux du bout bas sont arrondis à 5 mm et les arêtes longitudinales de la pente à 4 mm ; les arêtes du dessus au bout bas restent vives de part et d'autre de la fente. À l'impression : Imprimer la pièce retournée : la face du dessus de la base forme alors un pont de 21 mm. Vérifier l'écart des lèvres sur le premier exemplaire avant de lancer une série : c'est lui qui règle le maintien sur le rail. Le renfort reste dans le Ø28 de la collerette et ne crée pas de débord latéral. La rampe très courte et raide peut forcer sur les fils ; le canal de Ø6 mm limite la matière disponible à l'extrémité basse. Le modèle n'a pas été imprimé ni essayé sur un rail réel ; un léger écart de retrait suffit à changer le glissement.

Modular Cat Puzzle Scratcher
A modular puzzle and scratcher assembly designed to keep a cat engaged while filing their nails. The unit bolts together in layers, enclosing a labyrinth meant to hold treats or toys. The stack consists of four distinct pieces: Base Plate: Features a recessed pocket to accurately seat the scratch tray. Filing Tray: A removable insert that sits at the bottom of the maze, complete with a finger hole for easy swaps. Maze Walls: A 20mm deep labyrinth structure with reinforced corner bosses for clamping force. Top Plate: Incorporates multiple circular and elongated paw cutouts to allow access to the maze below, plus a dedicated raised ribbed section for exterior nail filing. Designed to be clamped together using four M4 bolts passing through all outer corners. Note that the provided file lays out the parts in an exploded view to clearly show the internal structures.
Kawasaki z1100 bar end mirror handle bar adaptors
A threaded adapter that steps an M18x1 fine-pitch external thread down to an M6x1 internal thread, made for fitting bar end mirrors to the handlebars of a Kawasaki Z1100. The stud is 16 mm tall with no flange, and a 10 mm hex socket in the base lets it be driven in with an Allen key. Remix hooks Hex socket size and depth: 10 mm across flats, 5 mm deep. A deeper socket (7 mm was the earlier value) grips a key better but leaves less solid material around the M6 thread. Change the across-flats value to match a different key. Overall height: 16 mm. Taller gives the mirror stem more thread to bite into; shorter reduces how far it protrudes from the bar end. Thread fit: both threads are modelled at nominal size. FDM usually needs 0.1–0.2 mm of adjustment on the M18x1 outside and the M6x1 inside, so print a short test ring first. Add a stop: there is no flange, so insertion depth is set by feel. A thin collar or a shoulder on the mating part would give a hard stop. Pairs with: a lock nut or thread-locking compound on the M6 side to keep a mirror from backing out under vibration. Starting dimensions External thread: M18, 1 mm pitch Internal thread: M6, 1 mm pitch, through the full height Height: 16 mm Socket: 10 mm hex, 5 mm deep Check the thread on your actual bar ends before relying on it. Print in a tough material such as PETG or ABS, since the part sees vibration and weather.
Dollhouse Slide Flume
Standard toy slides are straight ramps that launch figures directly into the floor. This provides a controlled descending flume with a banked S-curve approach, catching the speed before the drop ends. Fit & Print Specifications Interior Flume: 68 mm wide, accommodating standard 1:6 and 1:12 scale articulated figures. Sidewalls: 14 mm retaining walls above the floor, filleted internally at an 8 mm radius to prevent snags. Clearance: Reaches 260 mm outward and drops 450 mm vertically. Integration: Raw cut ends ready for friction mounts, threaded brackets, or platform adhesives.
