A CoinCube for every occasion

Anime.

Halloween.

Summer.

Space.

Christmas.

Companies.

...and everything you can imagine.

You only need to change the four skins to get a completely new CoinCube

A design built to last

The skins fit by pressure into a 2 mm recess, providing a clean and precise fit

For easy removal, the Core incorporates small internal holes that allow them to be pushed from the inside without damage

Depending on the use you want to give it, you can install the top cover with a slot to use it as a piggy bank or mount the trim to convert it into a pen holder, plant pot, organizer, or any other accessory

These pieces are fixed with a few drops of cyanoacrylate to achieve a solid and durable finish

Much more than a piggy bank

CoinCube can also become:

• Pen holder
• Organizer
• Container
• Plant pot
• Decorative item

Additionally, the bottom plug is fully customizable

All Core holes can be easily modified from your slicer to adapt them to your needs or even remove the bottom plug if your project does not require it

Quick installation

The skins are installed by pressure, without tools

To remove them, simply use the internal holes of the Core and gently push them outwards

You can change them as many times as you want without modifying the main structure

⚠️ Very important

After printing the Core, always print the calibration plate included in each skin collection

Depending on your printer's calibration, the filament used, or the print settings, it may be necessary to adjust a few tenths of a millimeter before printing the four final skins

This small step ensures a perfect fit
