<p>Mathematics is beautiful and a solid understanding of arithmetic is the basis for realizing it. With a pleasant physical representation, this design aims to provide a likable tool for understanding basic mathematical operations.</p><h2>Changes in v2</h2><p>As with the previous version cam grooves provide snap positions for the wheels and an inner compartment offers space for miscellaneous.</p><p>What changed:</p><ul><li>larger inner diameter of ⌀ 28mm <span style="background-color: rgb(255,255,255); color: rgb(32,33,34); font-size: 14px">≈</span> ⌀ 1.1inch</li><li>inner length increased to 111mm <span style="background-color: rgb(255,255,255); color: rgb(32,33,34); font-size: 14px">≈</span> 4.36inch (suits two times folded A4 or US-Letter paper formats and an IKEA pencil)</li><li>snap action now with three hardness levels</li><li>slightly larger grip area next to the wheels</li><li>printability</li></ul><p>A Braille Edition (6-point ICEB) is in progress.</p><h2>What to print</h2><p>For multicolor printing and convinience, a 3MF file is provided. There are several <strong>modifiers</strong> present, deactivate or change them to get your desired outcome.</p><p>The axle has multiple indicator styles available via modifiers. Directly painting the knurling pyramids in the slicer also produces beautiful pixelated works of art.</p><figure class="image image_resized" style="width: 70.03%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000510506/design/9653155d-a826-4894-9ad6-b96b0ff33834.webp"></figure><p>Also the wheels are offered with four different snap actions: light, standard, hard and fixed. → A light detent is recommended for stiffer materials like PLA and/or if an intended user has small hands.</p><figure class="image image_resized" style="width: 75.02%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000510506/design/2024-06-25_f2bc588cdf7c1.png"></figure><p>By choosing the type of modifier the wheels are also printable with or without ridges and embossed, flush or debossed symbols.</p><figure class="image image_resized" style="width: 75.03%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000510506/design/2024-06-25_b4fdc9cd68b9e.png"></figure><h2>How to print</h2><p>The design is optimized for an <strong>extrusion width</strong> of 0.21mm, 0.42mm and 0.63mm.<br>It also is divisible without remainder by any of the &#34;standard&#34; <strong>layer heights</strong> 0.08mm, 0.10mm, 0.16mm, 0.20mm, 0.24mm, and 0.30mm.<br>For a perfect result the first layer needs to match the other layer heights and needs to adhere well to the built plate. → Keep it slow at least for the first layer.</p><h2>Any chance to get it a bit different?</h2><p>Scaling it has partially been tested. A few % usually work well, please report back in case you tried.</p><p>The formula to scale this model to your desire is:</p><ul><li><i>[desired inner diameter in mm] / 28mm = scaling factor</i></li><li><i>[desired outer diameter in mm] / 45mm = scaling factor</i></li></ul><p>Blank wheels allow for custom modifications via the text shape tool of the slicer.<br>Remixes are not allowed, but if you feel like sharing parts with added/changed/customized details or fonts you&#39;re welcome to do so as print profile. - If in doubt, please ask beforehand.</p><h2>What next</h2><p>There may be improvements and modifications based on feedback given here.</p><p>Yes, there is a parametric system behind this design. Several things already have been published and more are planned to come online, your suggestions are welcome.</p><p>Maybe, take a look at <a target="_blank" href="https://makerworld.com/u/2797532051" rel="nofollow noopener">my other designs</a> ;-)</p>
