Modular small parts organizer

<p>The goal of this storage system was to have</p> <ul> <li>individually removable bins</li> <li>a size reasonable for small mechanical / electronic parts (large enough for m3 screws, small enough that m2 nuts don't waste a lot of space)</li> <li>a space efficient way to store multiple boxes</li> <li>relatively fast / efficient printing options</li> </ul> <p><strong>File naming</strong><br/> There are 2 different base sizes available: 10mm x 10mm and 15 mm x 15 mm. These base sizes determine the sizes of the different insets.</p> <p>I.e. for 10 mm x 10 mm the insets can be:</p> <ul> <li>10 mm x 10 mm</li> <li>10 mm x 20 mm</li> <li>10 mm x 30 mm</li> <li>20 mm x 20 mm</li> <li>...</li> </ul> <p>Whereas for 15 mm x 15 mm it would be:</p> <ul> <li>15 mm x 15 mm</li> <li>15 mm x 30 mm</li> <li>15 mm x 45 mm</li> <li>30 mm x 30 mm</li> <li>...</li> </ul> <p>All other measurements are based on these base sizes.<br/> A shell of <code>size-10x10-shell-6x4</code> will be roughly 60 mm x 40 mm big and fit for example 3 2x4 insets.</p> <p>The racks have an additional parameter <code>height</code> which is the maximum height a shell can have and still fit into a slot and <code>levels</code> which is the number of shells that can fit into the rack.</p> <p><strong>Custom sizes</strong><br/> For custom heights you can cut off the top of the outer shell and the bins using the <code>cut</code> tool in PrusaSlicer. Don't just rescale them, since this will mess up the pattern on the bottom of the bins/shell, that aligns the bins in a grid if there are gaps.<br/> The bins should be about 1.2mm less tall than the outer shell</p> <p>You can also use the included openscad file to create your own custom sizes. The code is a bit messy (especially for the rack), but it should work for most reasonable settings.<br/> This way you can also increase the resolution of the 3D models, Due to size constraints they had to be rendered a bit low.</p> <p>Using this bash script you can auto generate all files included in this print from the openscad source.</p> <p>``</p> <h3>!/usr/bin/env bash</h3> <p>set -eu</p> <p>outputDir=${1:-"./out"}</p> <p>declare -A names=(<br/> [0]="inset"<br/> [1]="shell"<br/> [2]="lid"<br/> [3]="rack"<br/> )<br/> sizes="10 15"<br/> heights="15 30"</p> <p>binary="openscad"<br/> if command -v openscad-nightly &amp;&gt; /dev/null<br/> then<br/> echo "Found nightly build of openscad, using it instead"<br/> binary="openscad-nightly"<br/> fi<br/> if ! command -v $binary &amp;&gt; /dev/null<br/> then<br/> echo "No openscad binary found"<br/> exit<br/> fi</p> <p>function callOpenscad {<br/> local baseSize=${1}<br/> local height=${2}<br/> local type=${3}<br/> local length=${4}<br/> local width=${5}<br/> local levels=${6}</p> <p>declare -a typeName=(${names[$type]})<br/> local outputName="${typeName}-${length}x${width}-${levels}.stl"<br/> local outputFolder="${outputDir}/size-${baseSize}"</p> <p>if [ ${type} = 3 ]; then<br/> local outputName="size-${baseSize}x${baseSize}-${typeName}-${length}x${width}-h${height}-${levels}-levels.stl"<br/> else<br/> local outputName="size-${baseSize}x${baseSize}-${typeName}-${length}x${width}.stl"<br/> fi</p> <p>mkdir -p ${outputFolder}<br/> nice -n 15 $binary \<br/> -D "invokedFromShell=1"\<br/> -D "baseSize=${baseSize}"\<br/> -D "height=${height}"\<br/> -D "type=${type}"\<br/> -D "length=${length}"\<br/> -D "width=${width}"\<br/> -D "levels=${levels}"\<br/> -o "${outputFolder}/${outputName}" modularBoxes.scad<br/> echo ""<br/> sleep 1<br/> }</p> <p>function generateInset {<br/> local baseSize=${1}<br/> local height=${2}<br/> local length=${3}<br/> local width=${4}</p> <p>callOpenscad "${baseSize}" "${height}" 0 "${length}" "${width}" 0<br/> }</p> <p>function generateOuterParts {<br/> local baseSize=${1}<br/> local height=${2}<br/> local type=${3}<br/> local levels=${4:-0}</p> <p>callOpenscad "${baseSize}" "${height}" "${type}" "3" "3" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "4" "4" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "6" "4" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "6" "6" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "8" "6" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "8" "8" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "12" "8" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "12" "12" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "16" "8" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "16" "12" "${levels}"<br/> callOpenscad "${baseSize}" "${height}" "${type}" "16" "16" "${levels}"<br/> }</p> <p>function generateInsets {<br/> local baseSize=${1}<br/> local height=${2}</p> <p>generateInset "${baseSize}" "${height}" "1" "1"<br/> generateInset "${baseSize}" "${height}" "1" "2"<br/> generateInset "${baseSize}" "${height}" "1" "3"<br/> generateInset "${baseSize}" "${height}" "1" "4"<br/> generateInset "${baseSize}" "${height}" "2" "2"<br/> generateInset "${baseSize}" "${height}" "2" "3"<br/> generateInset "${baseSize}" "${height}" "2" "4"<br/> generateInset "${baseSize}" "${height}" "3" "3"<br/> generateInset "${baseSize}" "${height}" "3" "4"<br/> generateInset "${baseSize}" "${height}" "4" "4"</p> <p>}</p> <p>function generateSet {<br/> local baseSize=${1}</p> <p>generateInsets "${baseSize}" "30"<br/> generateOuterParts "${baseSize}" "30" 1<br/> generateOuterParts "${baseSize}" "30" 2</p> <p>for height in ${heights}<br/> do<br/> for i in 2 3 4<br/> do<br/> generateOuterParts "${baseSize}" "${height}" 3 "${i}"<br/> done<br/> done<br/> }</p> <p>for size in ${sizes}<br/> do<br/> generateSet "${size}"<br/> done<br/> ``</p> <h3>Print instructions</h3><p>The wall and bottom thickness are optimized for 0.2mm layer height and 0.45mm line width (default for the 0.4mm nozzle). 0.3 mm layer height should also work well.</p> <p>Since the lid and the outer box have a 3 line wall thickness, it is recommended to the switch on the advanced option <strong>detect thin walls</strong>, this will speed up the printing process, and should result in a nicer finish.</p> <p>If the lid is printed in a clear material (For example Colorfab XT or FormFutura HD Glass) it should be thin enough to make out some details through it.<br/> A good way to group the bins is by adding a manual color change for the last few milimeters.</p> <p>Since the lid is friction fitted, you might have to scale it a bit up or down, depending on your printer and the shrink factor of your material. These adjustments shouldn't be more than a militmeter, and shouldn't affect the print quality.</p>
