Modular Jewelry Box

I have developed a jewelry box that is modular and freely expandable

The basic model consists of five drawers stacked on top of each other and an upright chain compartment

All elements are equipped with a push-to-open function

so the box maintains a clear, handle-less look from the outside

With a targeted press on the front, the respective drawer opens a bit

allowing it to be easily pulled out afterwards

Various inlays are provided for the drawers, allowing for flexible jewelry storage

Whether compartments for rings, dividers for earrings, or larger compartments for other pieces of jewelry – the inserts can be exchanged as needed and will be supplemented step by step

The chain compartment also works with push-to-open

With a press on the top visible surface, the pull-out moves upwards

Hooks are attached to the underside of this plate, where chains can be neatly hung and stored

This prevents chains from tangling or lying around messily

It is important to guide the pull-out upwards with your finger when opening it, as it otherwise springs up quite quickly

The jewelry box is primarily designed so that the height of five drawers exactly matches the height of the chain compartment

The expansion is mainly intended for sideways arrangement, so you can easily place several modules next to each other

If you don't want to use the chain compartment, you can, of course, stack the drawers higher or alternatively place the chain compartment separately

The construction is designed so that almost all parts are simply plugged together

Only the drawer slides are fastened with small screws to allow for a clean full extension with a stop

Everything else holds via plug connections

The Push-to-Open mechanism is particularly important
In my tests, it has been shown that this does not work with normal PLA. Due to continuous stress, the thin rods break or deform after a short time. While PLA-CF is more stable, it does not always work reliably – sometimes it runs smoothly, sometimes it jams or still breaks after some use

Therefore, I am working on testing the mechanism with more stable materials. Filaments with fiber additives, such as PA6-CF or Nylon, but also PETG-CF or PETG-GF, are particularly suitable. Such materials are significantly tougher, withstand continuous stress better, and do not deform as quickly as PLA. In principle, another very stable material without additives can also work if it is designed for mechanical loads

For anyone who wants to print the project already, the following applies: The push-to-open parts should absolutely be made with a reinforced or very stable material. If you have different filaments at home, feel free to try them out and provide feedback if any problems arise

If dimensional deviations occur due to other materials, I will adjust the model as needed so that it functions properly

In short: PLA is unsuitable, PLA-CF is only of limited use. Materials with fiber additives (CF/GF) or generally robust technical filaments are recommended

This results in a modular jewelry box that is functional, flexible, and at the same time visually tidy

Update V1.001.00 – Spacer for the chain compartment

There is now an 18 mm high spacer. This raises the spring slightly

allowing the pull-out to come further up when extended, providing more space to hang chains

The spacer is inserted as shown in the picture

Important: Be careful when sliding it on – the rod onto which the part is placed

can break very easily. If this happens, the entire part must be reprinted
