CAD for 3D printing,
without learning CAD.
Fusion 360 and OpenSCAD take weeks before your first usable part. Describe what you need instead and get a print-ready 3D file with real dimensions and tolerances.

The learning curve
The part is simple. Traditional CAD is not.
You need a bracket with the right hole spacing, an enclosure that fits a known board, a replacement clip. The geometry is trivial, but sketches, constraints, extrudes, and fillets stand between you and a printable file. Most makers give up before the first print.
So we removed the software. You describe the part. The AI compiles it, to real millimetres.
How it works
Describe it, tune it, print it
- 1
Describe the part
Say what it is, the dimensions, the hardware it must fit.
- 2
Tune every dimension
Every measurement becomes a slider, and tweaking is free.
- 3
Download and slice
A slicer-ready 3MF or STL, 1:1 in Bambu Studio or Prusa.
Real measurements
Built in actual millimetres
Ask for a case that fits a specific board and it looks up the spec, lays out mounting standoffs and connector cutouts, and shows the dimensions right on the model before you download.
- Looks up real part specs, not rough guesses
- Dimensions shown on the model in the viewer
- Tolerances tuned for FDM so holes and fits print true
One tool, the whole job
No stack of apps to stitch together
Modeling, editing, mesh repair, and export usually mean three or four programs. GrandpaCAD does the whole job in one chat, and checks its own work before it hands you the file.
- Model, refine, and export without switching tools
- It repairs and validates the mesh automatically
- Bring an existing STL or 3MF and change it in place
Pick the path that fits how much time you have
Traditional CAD software is powerful and worth learning if you'll use it every week. If you just need the part, there's a faster road.

Izdelano za mojega dedka
To orodje je bilo ustvarjeno za mojega dedka, ki obožuje 3D tiskanje, vendar ima težave s kompleksnimi programi za modeliranje. Ne govori angleško, zaradi česar je večina orodij za 3D oblikovanje zanj nedostopnih.
Kljub tem izzivom je navdušen nad ustvarjanjem 3D tiskanih modelov za našo družino. Uporablja svoj BambuLab A1 tiskalnik in zdaj lahko preprosto ustvarja prilagojene modele z enostavnim opisovanjem tega, kar želi.

Ena generacija, ena cena
Štejete modele, ne kreditov.
Druga orodja umetne inteligence zaračunavajo kredite, zato en model postane niz plačil po ceni, ki se spreminja glede na paket. Mi preprosto štejemo cele modele, prilagajanje pa je brezplačno.

Common questions
What's the easiest CAD software for 3D printing?
For most makers, the easiest CAD is no CAD: describe the part in a chat and let the AI model it. Tinkercad is the easiest traditional option but tops out quickly on precision. Fusion 360 and OpenSCAD are powerful, and both take weeks to get productive in.
Is there free CAD software for 3D printing?
Yes. Tinkercad, OpenSCAD, and FreeCAD are free, and Fusion 360 has a hobbyist license. GrandpaCAD gives you 3 free generations with no credit card, so you can compare the describe-it route against learning a tool before spending anything.
Can it really hit exact dimensions?
Yes. Give dimensions in your message and they land in the model as real millimetres. The AI also looks up specs for known hardware (boards, screws, bearings) and applies FDM-friendly tolerances so printed holes and fits come out true.
What file do I get for my slicer?
A 3MF or STL that loads 1:1 in Bambu Studio, PrusaSlicer, and Orca. OBJ, GLB, and GLTF exports are there too if you need them.
What if the first result isn't right?
You iterate in the same chat: point out what's off and it regenerates. Every dimension is also exposed as a slider, and slider tweaks never cost a generation.
