drawers with inlay-shelves for Raaco 150 and Powerfix magazines

thingiverse

When you have a hobby that requires a lot of small parts, like electronics, you may already have several magazines that are filled with resistors and capacitors, different semiconductors and many small mechanical parts like switches, connectors, jumpers, small nuts and bolts. Especially when you develop you own stuff, you want to be prepared and you probably 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 have drawers that can be divided into 2 to 4 compartments and 8 rows of 4 to 5 drawers. This gives a maximum space for 854=160 different values. An E24-series from 1Ω to 10MΩ has 192 values and would thus exceed one Raaco-magazine. Most of the space in such a magazine is occupied by air and it is obvious that more compartments per drawer is the solution. The standard partition walls for the drawers in the usual small parts magazines divide in one dimension, from back to front. These drawers here divide into 3 dimensions. We have rows and columns and levels in the shape of inlay-shelves. In Raaco- and Powerfix-magazines they can be removed and they typically slip out when two neighboring compartments are filled with 1000s of smallest parts and you want wo take out one of them. Thus the partition walls are fixed. The ability to print them yourself gives enough flexibility. If you download and unpack the .zip-File, you can choose one of the pre-built STL-files which are named this way: _xx.stl for the drawer _xx-inlay.stl for one shelve. The default values in the file are for Raaco 150-0 drawers. If you want to Create a Powerfix drawer, you can use the outcommented values in the .scad-File or you can use the following Values in customizer: width = 68; height = 36; length = 118; grip_depth = 8; grip_height = 8; grip_frontheight = 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 want to store electrostatic sensitive devices, I suggest to spray the insides with graphite lacquer as you can see on the first image.
