01 /The design

A small building for spare change.

Two stepped building levels, rows of windows and the Fort Knox entrance lettering give the piggy bank its architectural character. The gallery shows the rear, entrance detail and underside access panel.

At the 3 mm material scale, the finished bank is 200 mm wide, 200 mm long and 102 mm high. The package includes cutting files for 3 mm and 1/8-inch plywood and a PDF assembly guide.

The design turns a miniature building into a piggy bank.

02 /At your workbench

Choose your material.Make it fit.

01 /

Measure first.

Check your actual material thickness and the matching file version. Test the slots and kerf on a small cut.

02 /

Check the layout.

Open the supplied design in compatible laser software. Check that the layout fits your machine’s usable work area.

03 /

Follow the guide.

Use the PDF assembly guide to identify the parts and work through the construction sequence.

Plan this build.

Measure your plywood and use the matching version. Test the fitted connections and access panel before finishing the model, then follow the guide through assembly.

At the 3 mm material scale, no individual part exceeds 290 mm. This refers to one part, not the assembled model or the whole cutting layout. Rescaling changes that limit.

Is this a working safe?

It is a wooden piggy-bank model styled after Fort Knox. It is not specified as a lockable safe or secure storage device.

What do I receive?

Digital SVG and DXF design files and a PDF assembly guide. No physical model, material or hardware is shipped.

Can I change the scale?

Scale every part equally. Slots and tabs change with the design, so the material thickness must change in the same proportion; the finished dimensions also change. Test the fit and kerf before cutting all the parts.

Can I use the design commercially?

Contact 21CNCStudio to discuss permission before commercial use. Do not redistribute the digital files without the author’s permission.
