drawers with inlay-shelves for Raaco 150 and Powerfix magazines

thingiverse

When you have a hobby that demands a multitude of tiny parts, like electronics, you may already possess several magazines packed with resistors and capacitors, various semiconductors, and numerous small mechanical components such as switches, connectors, jumpers, tiny nuts, and bolts. Especially when developing your own projects, you want to be well-prepared and likely have the standard components in all values, typically the E12-series for carbon resistors and the E24-series for SMD-resistors. Typical small parts magazines feature drawers that can be divided into 2 to 4 compartments and 8 rows of 4 to 5 drawers. This results in a maximum space for 854 unique values. An E24-series spanning from 1Ω to 10MΩ boasts 192 values, thus exceeding one Raaco-magazine capacity. Most of the space in such magazines is taken up by air, and it becomes evident that more compartments per drawer is the solution. The standard partition walls for drawers in common small parts magazines divide in one dimension, from back to front. These unique drawers, however, divide into three dimensions – rows, columns, and levels in the shape of inlay-shelves. In Raaco- and Powerfix-magazines, these compartments can be removed, but they tend to slide out when two neighboring compartments are filled with thousands of smallest parts and you want to take out one. Thus, the partition walls are fixed. The ability to print them yourself provides ample flexibility. If you download and unpack the .zip-file, you can select one of the pre-built STL-files, which are named accordingly: _xx.stl for the drawer _xx-inlay.stl for one shelf The default values in the file are set for Raaco 150-0 drawers. If you want to create a Powerfix drawer, you can use the commented-out values in the .scad-file or customize them with the following settings: width = 68; height = 36; length = 118; grip_depth = 8; grip_height = 8; grip_front_height = 26; grip_downshift = 1; griphole_diameter = 16; Print Settings Resolution: 0.2 Infill: n.a. Notes: The grip is designed to be printed without support. Post-Printing First, remove the brim, especially well on the inlay-shelves! If you plan to store electrostatic-sensitive devices, I suggest spraying the interiors with graphite lacquer as seen in the first image.
