Wheel parametric

prusaprinters

<p>Hi,</p><p>this is a replacement for a wheel of what you want it for. It is optimized for printing time and stability. It is work in progress, so i will optimize it further. Initially i designed this for my lawnmower. My neighbor asked me if this would fit on his barbecue, so i made this parametric.</p><p>It is parametric, what means you can customize e.g. the size of the wheel or the mount for different axle sizes. You only need to download OpenScad and uncheck In the Window menu, the option called [Hide customizer]. Then paste the code into editor, customize the variables, press F6 for rendering and export it as 3mf. Then load this file in you preferred Slicer and voila.</p><p>&nbsp;</p><p>If the file is not rendered, the view of the model lacks a bit. For quick rendering you can change the variable "ResCircle" from 1000 to 100 or so. But remember to turn it back, cause the model would lose details in such low resolution.&nbsp;</p><p>&nbsp;</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/72408/rich_content/17e0d4df-27f7-4671-8c00-cb25cfb40887/oscad.png#%7B%22uuid%22%3A%2246086d42-9d48-41ef-b90f-3c2fcef0a675%22%2C%22w%22%3A1235%2C%22h%22%3A1053%7D"></figure><p>&nbsp;</p><p>&nbsp;</p><p>The prepared 3mf examples are following this naming convention:</p><p>wheel_d180_a12_s30.3mf</p><p>Example:<br>Outer diameter: 180mm<br>Axle mount: 12mm (12.4 for tolerance)<br>Axle mount shaft length: 30mm</p><p>&nbsp;</p><p>&nbsp;</p><p>I measured the original axle of my Wolf lawnmower with 11.9 mm. After a testprint i adjusted the printfile for 12.4mm wich fits perfect for my needs.&nbsp;</p><p>The OpenScad file is attached for customization.
