100mm Concentric Breakaway Disc
Created today
Description
100mm concentric stepped disc connected entirely by breakaway tabs. Used to verify dimensional accuracy, extrusion multipliers, and single-wall adhesion on FDM toolheads.
Critical Fitment
- Outer Diameter: 100 mm exactly.
- Bridges: 0.6 mm wide (designed to lay down as 1 to 2 perimeters on a standard 0.4 mm nozzle).
- Clearance Gap: 1 mm radial gap between rings.
Notes
If the flow rate is dialed in, the rings will break away clean under manual pressure. If the printer over-extrudes, the bridges will fuse solid and refuse to yield. Standard 3 mm thickness flat stock — do not run on a raft.

dome 3
A plain flat disc in the spirit of an oversized washer or a vinyl-record blank: 3 inches across, 1/8 inch thick, with a clean 1 cm hole through the centre. Prints flat with no supports.

Zauberstab Verschluss 3.1
Zweiteiliger, hohler zylindrischer Testkörper zur Prüfung von FDM-Toleranzen. Beide Teile verfügen über eine geschlossene Außenwand und schließen bündig ab. Feste Abmessungen: Außen 30.8 mm, Innen 21.8 mm Mindestwandstärke: 1.5 mm im kritischen Bereich der Nuten Mechanismus: Bajonettverschluss mit Arretierungsnocke gegen unbeabsichtigtes Öffnen Druckbar: Ohne Stützstrukturen, flach auf dem Druckbett positioniert
20 mm Round Disc, 2 mm Thick
A flat 20 mm round disc, for when a 2D circle needs to become something you can print and hold. A bare circle has no thickness, so this gives it enough to print as a solid piece. Print details Diameter: 20 mm Thickness: 2 mm (assumed, since a plain circle has no height) Sits flat on the bed, no supports needed Prints in any filament
Plush Canvas Boundary Gauge
A stark, unyielding boundary for plotting out your plushie features. This gauge isolates a perfect 100 by 100 millimeter square, stripping away the bulky machine clips and mounting hardware of a traditional Janome SQ10b hoop to leave only the raw workable area. Pressed directly against a curved fabric face, it frames exactly where the needle can reach before the machine ever turns on. Internal Canvas: Exactly 100 × 100 mm with dead-sharp corners to preserve the true bounding box. Outer Profile: 120 × 120 mm with gently eased 3 mm corners to prevent snagging the pile. Gauge Thickness: A low-profile 3 mm drop, stiff enough to frame the fabric without bowing.
SumaSlide — Tablero Matemático con Carriles
SumaSlide convierte la abstracción de las sumas con llevadas en un proceso mecánico y tangible. Diseñado con tres vías de deslizamiento fresadas en la base, permite que la ficha del "1" sobrante viaje físicamente hacia arriba y a la izquierda hasta coronar la columna siguiente. Esta versión ajusta la cabecera e incorpora un módulo de test para verificar tolerancias de deslizamiento antes de lanzar el tablero completo. Ajustes y Componentes Pieza de prueba: Tramo corto con curva idéntica a la principal, ideal para comprobar que las fichas fluyen sin atascos. Cabecera rediseñada: Texto encogido y desplazado al borde superior para garantizar un recorrido limpio y seguro. Separación de objetos: Todo está dispuesto en una misma plataforma virtual; divídelo en objetos independientes desde tu fileteador para imprimir por separado.
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.
