Arrange your 3D models on a virtual print bed and check they all fit before you start printing — saves wasted prints.
What this tool does
Load 3D models onto a simulated print bed, drag and arrange them, and preview the build volume to confirm everything fits within your printer's dimensions. Helps plan optimal placement for multi-part prints.
Who this is for
3D printing enthusiasts maximising plate efficiency
Makers printing sets of parts in a single run
Designers checking build volume constraints before printing
Technicians managing batch print jobs
How to use this tool
Load one or more 3D model files onto the virtual bed
Drag to position and rotate models
Check the highlighted build volume — red means out of bounds
Arrange until all parts fit, then print with confidence
Inputs
3D model files — OBJ or STL files to place on the bed
Printer dimensions — Width × depth × height of your print bed
Spacing preference — Minimum gap between models
Outputs
Visual layout — Confirmed arrangement to replicate in your slicer
Build volume check — Confirmation all parts are within bounds
Example use cases
Chess set — Arrange all 32 pieces across multiple plates before starting a 4-day print
Product parts — Check a 10-part enclosure fits in a single plate
Gift batch — Plan a Christmas ornament run for maximum plate usage
Prototyping — Confirm a new part fits your printer before slicing
Enter any printer's build volume dimensions manually — it works with any FDM or resin printer.
▶ Can I import STL files?
Yes — OBJ and STL are both supported.
▶ Does it export a plate layout file?
Not yet — replicate the shown arrangement in your slicer (Cura, PrusaSlicer) manually.
▶ How many models can I load at once?
As many as your browser handles — tested up to 20 simultaneous models.
