Rail system/retractable spice rack

thingiverse

Human: *small bugfix, on the bottom board the mounting brackets were off center* First of all, I want to thank Ken9226 for uploading the spice holders: www.thingiverse.com/thing:2763553 This is my second contribution, currently learning FreeCAD. I wanted to create a retractable spice rack to save space in my kitchen. Then I realized that the rail system can be used for many things. In my setup, I will have 2 double racks and a single rack, the double and single bottom board are included. The standing board is too big for my printer so I didn't bother designing it with holes and stuff. I will use an 8mm wooden board, cut to size. The linear movement is 290mm (11.5")with an inner wheel spacing of 50mm(1.97") (standard upper cupboard in europe is 300mm (11.8")) The built-in length is 220mm(8.7"). The shafts for the inner wheels are M4 threaded rods (1/16"), mounted in the bottom board, then placed the spacers and then the ends are placed inside of the inner wheels. The shafts of the outer wheels are screws M4x15 (1/16x0.6) for the wall mount and threaded rods M4x40 (1/16x1.6) on the bottom mount if you use a double rail or M4x30 (1/16x1.18) if you use a single rail. Mounted with Nylock nuts. The bottom mount is made in such a way that you can mount wheels double sided or single sided. Also, for the spacing from the bottom board to the inner wheels I designed spacers so you can easily extend them to increase the spacing. Also the bottom and wall mount are designed in a way that you can strengthen them by scaling the thickness. The rail can be scaled as well without losing functionality. For one set you need 2 mounts (e.g. wall and/or bottom), 4 inner wheels, 4 spacers, 8 outer wheels, 2 rails, 2 cover plates, optional: bottom plate. I hope it is useful for you.
