Print what you need, in the size you need
Hardware stores sell parts in the sizes they stock. Our generator makes them in the size you measured. Choose a template, enter your dimensions, check the part in 3D and download a ready-to-print STL — right in your browser, with nothing to install.
How it works
- Pick a group and a template — over 50 templates in twelve groups, from storage boxes to gears.
- Set your sizes — sliders and fields for every dimension, with a live 3D preview. Add text, choose fonts and upload your own images where it makes sense.
- Download and print — export the STL and slice it as usual. Save your settings to come back later.
Why our templates
- Made for FDM printers. The templates are designed to print without supports: holes point up or get pointed roofs, overhangs stay within 45° (short bridges where nothing else works), and load-bearing parts are laid out so the layers follow the load.
- Sized for real printers. Defaults fit common 256–300 mm beds; larger parts are possible.
- Fits on the first try. Clearances for threads, lids and snap fits are adjustable — print the calibration test once and use your printer’s values everywhere.
- Runs in your browser. The full OpenSCAD engine runs on your device; your settings and images stay with you.

Frequently asked questions
Do I need to install anything?
No. Everything runs in your browser. A recent desktop browser works best; large or detailed parts render faster on a computer than on a phone.
Which printer and material should I use?
The templates are made for FDM printers with a 0.4 mm nozzle. PLA is fine indoors; use PETG or ASA for outdoor parts, warm places and parts under load, and TPU where a part should flex.
A lid, thread or clip is too tight. What now?
Raise the play or clearance setting of the template by 0.05–0.1 mm and print again. The Printer Calibration template shows which value your printer needs.
Can I save my settings?
Yes. Your last settings are remembered in the browser, and Save parameters downloads them as a file you can load again later.
Can I use my own images, SVGs or STLs?
Where it makes sense: lithophane photos for ornaments and night lights, a logo for the phone holder, SVG outlines for cookie cutters and STL inserts for ornaments and phone holder supports.
