Small Screw Management System for Makers

<p><strong>Update: Sept-22: Bearing folder added with longer label for boxes. Added M2-4 &amp; M4-20&amp;35. 35 has a double long box.</strong></p><p>Working on recent projects, I needed a better management system for small screws than my egg cartons. I used this system in building some 3D printed RC cars. The small 30x30mm boxes hold various screws and are labeled for quick identification. A bottom plate (cabinet) is ridged and holds 6 boxes together in one group. There are slots under each box that fit into the ridges on the cabinet. An identical plate can be placed on top and the set can be bound together by two rubber bands. Simple and easy.&nbsp;</p><figure class="media"><oembed url="https://youtu.be/WuTAN8Qlc4M"></oembed></figure><p><i><strong>Printing</strong></i><br>0.3 layer height is all you need. You can use 0.2 if you want better walls, but you'll see some ghosting on the walls from the label section. It is a tradeoff between wall thickness and wall quality.&nbsp;</p><p>PLA material (any other will work fine)</p><p>I used 4 perimeters(wall) so there is no infill on walls. 20% infill is fine. I used gyroid. Use at least 3 bottom layers.</p><p><i><strong>Notes</strong></i><br>2 color box requires filament change near top layers. This can easily be done in Prusa Slicer and a single extruder system.</p><p>Top number (10) and bottom number (2) indicates this box holds M2x10mm screw.&nbsp;</p><p>Differing box colors can be used &nbsp;to identify similar characteristics among parts. For instance, my M3 screws are all in gray boxes with blue lettering. All my 3mm rods use a different color box from the screws.</p><p>A set consists of a bottom plate, 6 boxes (filled with screws or other small parts) and a top plate. The bottom plate can have 4 feet glued into holes in the bottom of the plate. A set can then be stacked on top of another set. For moving, you can wrap two rubber bands around the sets. No screws will escape by shaking. If you don't want to use feet and want to stack boxes, you can create a divider between the sets by gluing two identical plates back-to-back.</p><p>I also have a small bit holder that I find useful to save space on my workbench when assembling certain projects: &nbsp;<a href="https://www.printables.com/model/282031-drill-holder-for-m2-m4-projects">https://www.printables.com/model/282031-drill-holder-for-m2-m4-projects</a>&nbsp;</p><p>&nbsp;</p>
