The tools a print needs, where Tinkercad stops.
Every feature in PrintXO starts from how prints go wrong: parts that won't screw together, models bigger than the bed, a mount that snaps at the screw hole.
Threads that fit
Metric bolts, nuts, rods and threaded holes from M3 to M42, cut with a true 60° profile. One clearance setting tunes every thread and joint to your printer.
Bigger than your bed
Split any part across X, Y or Z. PrintXO finds room on the cut face for pegs, dowel holes, magnet pockets or a screw joint, then lays both halves flat on the bed.
Strength where it counts
Draw a reinforce zone around a hinge or screw hole and give it its own infill and wall count. It arrives in your slicer as a modifier, so the rest of the part stays light.
Colour by part
Give each part a filament. The 3MF keeps the assignments, so a multi-colour print loads into the slicer ready to go.
Also in the box: push/pull sketching on the bed or any face, twist, taper and bend, an overhang check that shows where you'll need supports, lay flat on any face, patterns, mirroring, measuring and STL import.
From idea to slicer in four moves.
Sketch
Press R for a rectangle, C for a circle or L for lines. Type sizes as you draw.
Pull
Pull the outline up into a solid. Push it into a face and it cuts a hole.
Shape
Twist, taper and bend it, add threads and connectors, and mark where it has to be strong.

Questions
Which slicers does it work with?
The 3MF opens with filaments and reinforce modifiers in PrusaSlicer and OrcaSlicer. Bambu Studio, Cura and any other slicer can use the STL export, and Pro zips include the modifier shapes as separate STLs.
Where are my models stored?
In your own browser, saved as you work. Use Save to keep a project file on your computer and open it anywhere. Nothing is uploaded to us.
Does it work offline?
Yes, once it has loaded. Install it from your browser's address bar and it opens like a desktop app.
Do I need an account?
No. Pro is unlocked with the licence key you get by email after checkout. Paste it into PrintXO and you're done; a key works on up to three browsers.
