Customizable Toolbox Labels w/ Embedded Magnet

thingiverse

<h1>Overview</h1> This is a remix of the <a href="https://www.thingiverse.com/thing:2768920">toolbox labels created by benjamenjohnson</a>. I liked the design of his labels and the OpenSCAD/Customizer implementation. However, I did not like that he used magnetic tape for adhesion. This remix instead uses an embedded disc magnet (I used neodymium) to adhere the label to the toolbox. I have included several pre-made labels. For any other labels that you might want, feel free to use the customizer as described below. I hope that these are helpful. Please post your makes! <h1>Supplies</h1> <ul> <li><a href="https://www.homedepot.com/p/Master-Magnet-0-3-in-x-0-11-in-Neodymium-Rare-Earth-Magnet-Discs-10-per-Pack-07045HD/202526363">Neodymium Disc Magnets, 8mm diameter x 3mm thickness</a> (use any disc magnet that you want, this is just what I found at Home Depot)</li> <li>Super Glue (optional)</li> </ul> <h1>How to Print</h1> Printing these labels requires two pauses: one to insert the magnets and another to change the filament for the alternately-colored text. The process for this is as follows. <h2>Modifying the G-Code</h2> <ol> <li>The first pause must occur just before the slot for the magnet begins to cover over. To do this I used the <code>M125</code> G-code command in Marlin. This requires that <code>PARK_HEAD_ON_PAUSE</code> be enabled in your Marlin firmware. If it is not enabled, there are alternative commands which serve the same purpose. Regardless, identify the layer where the slot is covered in your slicer and insert the pause before this layer begins. For me, at 0.28 mm resolution with the default customizer settings, this occurs before layer 14 (counting from zero).</li> <li>The second pause must occur just before the letters begin printing so that you can change the filament color. For this, I used the <code>M600</code> command which requires that <code>ADVANCED_PAUSE_FEATURE</code> be enabled in your firmware. If this is not enabled, you can use one of the alternative filament change methods detailed elsewhere on the internet. At 0.28 mm resolution and default customizer settings, I placed this pause before layer 16 (again, counting from zero)</li> </ol> <h2>Printing</h2> <ol> <li>Begin the print with the desired base filament in the printer.</li> <li>At the first pause, insert your magnets of choice into the open slots in the print. Ensure that the magnets are properly oriented such that the downward face of the magnet attracts the desired adhesion surface instead of repelling it. Out of an abundance of caution, you can put a small drop of superglue in the slot before placing the magnet inside. This can help ensure that the magnet does not come out during printing, and also help to avoid a loose-fitting magnet if your air gap is too large. Then resume printing.</li> <li>At the second pause, change the filament to that desired for the lettering. If you have the <code>M600</code> command enabled in your Marlin firmware, this is a breeze. If not, it still is not too hard but you will have to do the research on the process for this. Be sure to purge the old filament, and then resume printing.</li> </ol> <h1>Customizer</h1> I built on <a href="https://www.thingiverse.com/benjamenjohnson/designs">benjamenjohnson</a>'s OpenSCAD code to create this. As such, the same rules that apply to his customizer also apply here. The label length must be set manually to accommodate the length of the text. Also, any lowercase lettering with hanging parts (e.g. "g", "q", "y", etc.) will hang off of the label. You could probably fix this issue in the OpenSCAD code if you felt so inclined. Otherwise, you can print with a support under the hanging lettering, use capital letters, or just avoid using these particular lowercase letters. I made it so that you can customize the size of your magnet and the size of the air gap around the magnet. These are all fairly self-explanatory when looking at the customizer/code.
