Wowstick case with magnetic bit holders, parametric

prusaprinters

<h3>Features</h3><ul><li>Holds 56 standard bits + 9 Long ones (my kit has 52+4, so there are slots to spare)</li><li>Holds the magnetizer/demagnetizer thingy</li><li>Has a small pocket for carying miscellaneous items, plus 7 more slots in the lid, where you can put screws when working</li><li>Magnets can be added mid-print to hold the bits in place more securely</li><li>Easily editable parametric design for Fusion 360</li></ul><h3>Origin story</h3><p>Ever since I got my <a href="http://alii.pub/69cp0x">Wowstick</a> I thought that the little storage tubes it came with, while pretty to look at, were a huge pain to use. What's more, the case that came with the kit could only fit the screwdriver itself and one of the three tubes. Needless to say, I soon set out to find the perfect 3D printed solution to this annoying problem. I was looking for something similar to the case that comes with the manual <a href="http://alii.pub/69cox1">Xiaomi precision screwdriver</a>, as I really liked how convenient it was to put in and take out the bits from it, because they were just laid out flat, rather than standing upwards in little holes. I also really wanted to mimic the magnetic functionality of the case, where you could easily flip it without the bits falling out. Unfortunately, having scowered PrusaPrinters and Thingiverse, I couldn't find anything that fit my criteria. I did find <a href="https://www.thingiverse.com/thing:3878265">a design</a> that was pretty good, but it had some things I didn't like (read my <a href="https://www.thingiverse.com/make:1014968">review</a> there if you are interested). It didn't have any source files, but <a href="https://www.thingiverse.com/thing:3680205/files">the model it was based</a> on did. I was going to modify that design, but it was not parametric at all, so I finally gave up and decided to remodel the whole thing myself and fix all the things that annoyed me.</p><h3>Print instructions</h3><ol><li>You will need 64 <a href="http://alii.pub/69cp39">7x1 mm disc magnets</a> for the whole thing, or just 24 if you don't care about magnetic bit holding. You can change the magnet diameter in the .f3d file if you have different ones.</li><li>You will need superglue to fix the magnets in place. Use a <strong>hex key</strong> when placing the magnets to avoid getting glue on your fingers.</li><li>The model is designed to print at 0.2 mm layer height and takes about 11 hours.</li><li>Print the small test model first to make sure your magnets and bits fit.</li><li>If you don't care about magnetic bit holding, go to step 8.</li><li>You will need to add a pause at the height of 5.6 to insert the bit holder magnets (see the pictures). The .gcode and .3mf files have the pause set up, you should see it in PrusaSlicer.</li><li>About 7 hours in, the printer will pause to let you insert the bit holder magnets. They will want to jump out of their holes and stick together, so you will need to superglue each of them into place. You could also make the holes tighter by editing the parametric file, but superglue will be easier and more effective if you have it. The holes are made to be 0.2 mm bigger than the magnets to make insertion easy, 0.1 mm would be quite a bit tighter.</li><li>After the print is done, insert 3 7x1 mm magnets (or 1 7x3 mm magnet) into each corner. MAKE SURE THE MAGNETS IN THE CORRESPONDING CORNERS ARE <strong>ATTRACTED</strong> TO EACH OTHER. You won't be able to remove them after they are glued, be extra careful here.</li><li>Clean up the top surface of both parts, if you want a better seal.</li><li>That's it, enjoy your new case!</li></ol><h3>Notice:</h3><p>Links to Aliexpress are affiliate, I get a small commission if you buy anything from them.</p>
