Based on the FreeCad model from _WG_, updated for FreeCad 0.20.
2 examples are included.
The 2 lines, 6 columns version is great to store your resistors.
Just install FreeCad if you have not :
https://www.freecadweb.org/downloads.php
Then open the “UltimateParametricDrawer_by_Willow.fcstd” file, edit the global spreadsheet by double-clic on it if you like to change the dimensions (like i did), edit the Settings spreadsheet to specify any number of rows or columns, the walls width, or the drawer's height.
You'll have to select the “ParametricDrawer” in the Tree view, then File→export, choose stl format, send the stl file to your slicer and Voilà !
Example shown is printed with recycled PLA, that's why it's quite ugly.
Houra to MarcElbichon !
