The GEN2 Modular System is a 3D printable storage solution offering ultimate flexibility and customization. Perfect for home users, hobbyists, and small businesses, so you can print exactly what you need and customize every piece to fit your space and style.

Unlike store-bought sets, GEN2 lets you print only what you need and expand your setup whenever you want. The drawers snap together seamlessly, giving you unlimited expansion possibilities. With the unique QuickLock mechanism, rearranging or relocating drawers is quick and effortless, so your storage can grow and adapt with you.

Case Extenders

GEN2 Case Extenders increase the height of your GEN2 Cases to create taller cubby storage bays. They’re designed for use with GEN2 Cubby Inserts, and you can stack multiple extenders to fit taller items like bottles and containers.
Note: These are not compatible with GEN2 Drawers

240 Collection

The 240 Collection is all about getting more out of your printer without changing a thing. Sized to match the build plates of popular machines like the Bambu X1C and Prusa Core One, these longer drawers give you extra storage in a single print, perfect for tools, parts, cables, or anything else that needs a dedicated space. Find all the 240 models HERE

STEP 1: Location

Decide how you would like to use your GEN2 storage. Keep in mind that the drawers are modular and can be easily swapped between under table and wall mount locations.

Find these kits at JERRARI3D/gen2-modular-system

UNDER TABLE (GEN2 RAILS)

Attach GEN2 drawers under any surface by installing the GEN2 RAILS. Once installed drawers can slide and lock into place, they can then be swapped out and rearrange in seconds

WALL MOUNT KIT - LITE

Mount GEN2 cases and drawers to almost any vertical surface using the GEN2 Wall Mount – Lite. Once installed, your layout is secure, modular, and easy to expand or rearrange anytime.
