<h3>Thin wall - calibration tool</h3><p>Figure out how thin a wall can get with your settings and how printing directions differ.</p><h3>&nbsp;</h3><h3>TLDR;</h3><p>With standard 0.4mm nozzle and "detect thin walls on" you can print 0.2mm thin single perimeter walls which are strong enough to build on them but act perfect as predetermined breaking point.</p><p>&nbsp;</p><h3>Why?</h3><p>For a project i needed internal breaking points, just strong enough to build structure above them but weak enough to get broken when you move the parts. Many articulated models use very raw structures for moveable parts that will work if the model is big enough, like the famous dragons or great friendly snakes. I needed internal wheels for parts as small as 10 mm and a lot of them in one model. That will not work with so much randomness, if just one fails or get broken the model is ruined. So i come to this research to figure out how small could a filament printed wall be.&nbsp;</p><p>&nbsp;</p><h3>Let's have a look:</h3><p>&nbsp;</p><p>0.4mm nozzle, PLA, 0,2 layer height.</p><p>The first model aligned XYZ to see if that matters.</p><figure class="image"><img src="https://media.printables.com/media/prints/239580/rich_content/704a2434-9c96-42ef-a2e8-c829d49f0bfc/20220708_150836.jpg#%7B%22uuid%22%3A%226843cc5e-5670-4444-a2bb-0a0f105fefb3%22%2C%22w%22%3A4032%2C%22h%22%3A1908%7D"></figure><p>You see that you don't see 0.05 and 0.10 mm, they can't be printed/sliced with a 0.2 resolution.
