project box generator
Project box generator
Make a 3D printable project box for your board. Set the board size, depth and walls, add a lid and a cable cutout, and download the STL. Free, no install.
Need more than sizes?
Ports in the right places, mounting holes, your logo on the lid. Describe it, and Voloom builds it from your sizes.
Good to know
Measure the board, not the box: the inside is the board plus the clearance on every side. The four screw posts stand in the inside corners, 6.5 mm in from each wall, so a board that fills the box needs notched corners or more room around it. The cable cutout is centered on the end wall and always stays between the posts and above the floor.
How it works
- 1Set the sizes and pick the options: screw-on lid, cable cutout, logo on the lid, logo horizontal, and text on the side. The project box rebuilds when you let go of a slider.
- 2Turn it in the preview and check the overall size.
- 3Download the STL or 3MF, one file per part, and slice it.
What you can change
Board length: 20 to 250 mm.
Board width: 15 to 200 mm.
Depth inside: 10 to 120 mm.
Room around the board: 0.5 to 5 mm.
Wall thickness: 1.6 to 5 mm.
Cutout width: 3 to 60 mm.
Cutout height: 3 to 40 mm.
Logo size: 20 to 90%.
Letter height: 3 to 20 mm.
Logo: upload your own SVG, or keep the Voloom mark.
Text: up to 24 characters.
When sizes are not enough
This is a real parametric model, built on a CAD kernel, not a mesh stretched to fit. Walls stay the thickness you set when the project box grows.
For anything the sliders do not cover, such as ports in the right places, mounting holes, text or a logo, describe it to Voloom. It starts from these sizes and builds the part from scratch.
About STL
STL (Stereolithography). The default 3D printing format since 1987: a bare list of triangles. Every slicer reads it, but it has no units, no color, and no parts.
Units: None in the file. Slicers read the numbers as millimeters. Up axis: Z. Opens in Bambu Studio, PrusaSlicer, Cura, OrcaSlicer, and Blender.
Questions
- Is the project box generator free?
- Yes. You get 3 runs a month without an account. Sign in with your email, free, and there is no limit.
- Do I need an account?
- No. Change the sizes and preview as much as you like. Downloads count toward the free runs; signing in, free, removes the limit.
- Can I add cutouts, holes or a logo to the project box?
- Yes. Use “Describe the rest” under the preview. Voloom takes your sizes into a prompt, you add what you need in plain words, and it builds a new parametric model you can keep editing.
- Can I get a STEP file?
- Yes, from the editor. Open your project box in Voloom and download STEP on the Maker plan, for Fusion, SolidWorks or FreeCAD.
