Create STL files online without CAD: 3D model configurator for spare parts and custom parts

You don't need CAD to create a Dimension part zu create: Mit userem 3D model configurator (parametric online configurator), you enter dimensions, check the live preview and export the STL online. After that you can use your spare part 3D have printed - e.g. Protective caps (also rectangular)holders, object holders or drilling templates/drilling plates.

What is it?

A parametrischer Online configurator is basically "CAD without drawing": You change parameters (e.g. diameter, wall thickness, depth, hole spacing) - and the 3D model adapts automatically. This is precisely why many users are looking for „3D model configurator“ or „3D configurator“, wenn sie fast ein Dimension part need.

When ist das ideal?
  • when you need a custom replacement part quickly
  • when you want to test variants (e.g. 0.2 mm more clearance)
  • if you want to create an STL file online without CAD skills

Typical custom parts without CAD

  • Protective caps / plugs (also rectangular): for profiles, tubes, furniture, covers.
  • holder: Schlauch-, Kabel- or Gerätehalter, Montagehilfen.
  • Object holder: simplee Aufnahmen, Clips, Führungen.
  • Drilling template / Drilling plate: holeraster, Anschläge, Senkungen – wiederholbar and exakt.
  • adapterdefine internal/external dimensions, set seat, export STL.

Tip: If you are not sure which template fits, start in the Configurator or write to us briefly via Contact.

STL online create: Schritt-für-Schritt

  1. template wählen (z.B. Schutzkappe, holder, Bohrschablone/Bohrplatte).
  2. Enter dimensions (Innen/Außenmaß, depth, Wandstärke, holeabstand).
  3. Allow for tolerance/clearance (siehe Tabelle bottom).
  4. Live-preview prüfen (fit, overhangs, stability).
  5. export STL and anschließend 3D printed.

tolerances (FDM): fits, die weklich funktionieren

For spare parts, the right Tolerance. These guide values will help you if you are configuring without CAD.

Fit Recommended addition Praxis-Note
Press fit +0.10-0.20 mm Für kurze/smalle Flächen. Testdruck empfohlen.
Plug fit +0.20-0.40 mm Standard für „passt gut and ist lösbar“.
Slip fit +0.40-0.60 mm Für bewegliche parte or häufiges Stecken.

Note: Depending on printer, nozzle, material and calibration. For critical parts: print a short test version first.

materialwahl: PLA, PETG, ASA, TPU

MaterialUseWhy sinnvoll
PLAInnen, prototypesDetailreich, fast, günstig
PETGAllroand-FunktionTough, more temperature resistant than PLA
ASAOutdoor/UVUV-resistant, weatherproof
TPUFlex-parteElastic, cushioning, non-slip

Printing tips for custom-fit spare parts

  • Wall thickness: lieber 3–4 Perimeter statt „massiv“ – stabil and oft günstiger.
  • Chamfers/Internal radii: erleichtern Montage and reyouzieren Klemmen.
  • Orientationalign clips/bars so that the layers are not "under tension".
  • boreen: oft minimal größer auslegen (z.B. +0,1–0,2 mm), dawith Nacharbeit sinkt.

FAQ

Can I weklich without CAD eine STL online create?

Yes, with a 3D model configurator you select a template, enter dimensions and export the STL. You do not need CAD software.

Which Toleranz brauche ich für eine Steckpassung?

Typically +0.20-0.40 mm (FDM). If it jams: Increase the clearance gradually by 0.1-0.2 mm.

Can I eine Schutzkappe (auch rechteckig) configure?

Yes, rectangular caps are a common application: define internal dimension + tolerance, select wall thickness, export STL.

Drilling template/drilling plate: What to look out for?

Adopt exact hole spacing, hole diameter usually +0.1 mm, and provide a flat support. Then the template is repeatable.

How starte ich am faststen?

Select template in configurator → enter dimensions → check preview → export STL → 3D order print.
