Helix Test Cube / Filament Sample / XYZ Calibration

prusaprinters

<p>I wanted to have a test print which I can use to test the dimensional accuracy of my printer and the print quality of my filaments. But it should also be pretty enough to keep as a color sample afterwards. So I created this <strong>30x30x30 mm</strong> cube which contains several functions.</p><p>The print takes about 1.5 hours.</p><p><strong>Below are pictures from which you can take some measurements to check your cubes for dimensional accuracy.</strong></p><p><strong>You can check the following properties on this cube:</strong><br>- stringing<br>- bridging (are the bridges over the letter clean, including the large area inside?)<br>- ghosting / ringing<br>- overhangs<br>- dimensional accuracy in all axes<br>- first layer height (is the logo clearly visible on the underside, are there holes in the narrow &nbsp; &nbsp; &nbsp; &nbsp; areas?)<br>- Was the helix printed neatly with a single wall line?<br>- Are there problems with the Z-seam due to the many retraction?<br>- Was the Z printed neatly on the top?</p><p>You can also try breaking out the Y, if that is too easy you may have to reduce the cooling or increase the printing temperature.</p><p><strong>Note:</strong> Since some people with a nozzle larger than 0.4mm had the problem that the slicer did not slice the Helix (minimum wall thickness for slicing) I added versions for 0.6mm and 0.8mm nozzles.</p><p><strong>Have fun printing and take a look at </strong><a href="https://www.prusaprinters.org/social/38556-3d-cave/prints?o=download_count"><strong>my other designs</strong></a><strong>!</strong></p><figure class="image image-style-align-center"><img src="https://media.prusaprinters.org/media/prints/69934/rich_content/d50620f8-373a-4469-b09a-eae22b1bf35c/screenshot-2021-06-26-201600.png#%7B%22uuid%22%3A%22e4824d67-6f7e-4baa-9166-4a8591a7b681%22%2C%22w%22%3A778%2C%22h%22%3A683%7D"></figure><figure class="image"><img src="https://media.prusaprinters.org/media/prints/69934/rich_content/46ca0a4e-2c71-42b2-b820-e8c1408696d3/screenshot-2021-06-26-201649.png#%7B%22uuid%22%3A%224e0441b5-7222-4eff-a484-6b22db702f6e%22%2C%22w%22%3A759%2C%22h%22%3A714%7D"></figure><figure class="image"><img src="https://media.prusaprinters.org/media/prints/69934/rich_content/822fff20-29c1-4e75-92d3-308f57eb73aa/screenshot-2021-06-26-201437.png#%7B%22uuid%22%3A%2232f24ab6-7603-401c-ac69-fa152cd9ae23%22%2C%22w%22%3A794%2C%22h%22%3A463%7D"></figure><figure class="image"><img src="https://media.prusaprinters.org/media/prints/69934/rich_content/86e4948c-efa8-416b-9736-52dd69279aa9/screenshot-2021-06-26-201520.png#%7B%22uuid%22%3A%22eccf41af-a087-4e83-aa9e-37cf69da20b3%22%2C%22w%22%3A775%2C%22h%22%3A693%7D"></figure>
