About this generator

Modelador 3D Modular Organizer is a browser generator for a drawer and workbench storage system. You choose a tray, a base grid or a fit-test kit. Trays are 1 to 8 by 1 to 8 modules of 42 mm, 2 to 14 height units of 7 mm, with 1 to 8 divisions in each direction; the tool refuses compartments smaller than 9 mm. You also set the outer wall, divider and floor thickness, the clearance between tray and base and the material (PLA, PETG, ABS or ASA), and there are shortcuts for screws, tools and a workbench base.

The download is an STL in a ZIP, with an optional technical sheet. The parts print flat without supports. It uses its own 42 mm interface: trays and bases made here fit each other, but the maker does not promise they fit other 42 mm systems such as Gridfinity, so print the 1x1 test kit first. You can also order the printed part in Brazil.

It comes from the small Brazilian studio behind the Modelador 3D Part Generator. The technical text is in Portuguese with menus partly translated, and downloads are free after registering a first name and a verified email.

What you can make

  • Drawer organizer trays with dividers
