TotBlocks

prusaprinters

<p>TotBlocks are a series of building blocks which can be used to construct the crystal structures of micas, pyroxenes, amphiboles, and other clay minerals. Source code, documentation, and support can be found here: <a href="https://github.com/derekdvleung/totblocks">https://github.com/derekdvleung/totblocks</a>.</p><p>&nbsp;</p><h3>Printing instructions</h3><p>The *.3mf files provided here are meant to be used for PrusaSlicer on a Prusa i3 MK3S printer. In particular, the files for the <i>O </i>modules (oblock) include support enforcers which may not be read properly by other slicing software! If using a different slicer, consider downloading the *.stl files from the GitHub repository. Use these settings at your own risk!</p><p>Layer height: 0.2-0.3 mm.&nbsp;</p><p>Brims are not recommended because these may be interfere with the pegs and slots. Instead, use a slow (5-20 mm/s) first layer speed.</p><h4>Supports</h4><p><i>O </i>modules: support enforcers only in PrusaSlicer (automatic supports in Cura seem to work ok)</p><p>Single octahedra: I usually print these without supports, but using supports should work as well.<i>&nbsp;</i></p><p><i>T </i>modules: no supports</p><p>Vertical pegs: supports everywhere</p><h3>Bill of materials</h3><h4>Starter set (can be used to build most of the structures)</h4><ul><li>4× oblock-m2-plus</li><li>4× tblock-n1-plus</li><li>4× tblock-n1-minus</li><li>4× oblock-m5-plus</li><li>4× tblock-n2-plus</li><li>4× tblock-n2-minus</li><li>4× single-octahedron</li><li>4× single-octahedron-clips</li><li>2× mica-connector (or the other connectors, depending on if the others should be printed)</li></ul><p>Additional blocks beyond the starter set are needed to build the orthopyroxene, protopyroxene, [clinojimthompsonite,] chesterite, sepiolite, and kalifersite structures.</p><h4>Mica group (2:1 phyllosilicates)</h4><ul><li>4× oblock-m5-plus</li><li>4× tblock-n2-plus</li><li>4× tblock-n2-minus</li><li>2× single-octahedron</li><li>2× single-octahedron-clips</li><li>2× mica-connector</li></ul><h4>Pyroxene group</h4><h5>Clinopyroxene</h5><ul><li>4× oblock-m2-plus</li><li>4× tblock-n1-plus</li><li>4× tblock-n1-minus</li></ul><h5>Orthopyroxene</h5><ul><li>4× oblock-m5-plus</li><li>4× oblock-m5-minus</li><li>8× tblock-n2-plus</li><li>8× tblock-n2-minus</li></ul><h5>Protopyroxene</h5><ul><li>4× oblock-m5-plus</li><li>4× oblock-m5-minus</li><li>8× tblock-n2-plus</li><li>8× tblock-n2-minus</li></ul><h4>Amphibole supergroup</h4><ul><li>4× oblock-m5-plus</li><li>4× tblock-n2-plus</li><li>4× tblock-n2-minus</li></ul><h4>Clinojimthompsonite</h4><ul><li>4× oblock-m8-plus</li><li>4× tblock-n3-plus</li><li>4× tblock-n3-minus</li></ul><h4>Chesterite</h4><ul><li>2× oblock-m5-plus</li><li>2× oblock-m5-minus</li><li>4× tblock-n2-plus</li><li>4× tblock-n2-minus</li><li>2× oblock-m8-plus</li><li>2× oblock-m8-minus</li><li>4× tblock-n3-plus</li><li>4× tblock-n3-minus</li></ul><h4>Palygorskite group</h4><ul><li>4× oblock-m5-plus</li><li>4× tblock-n2-plus</li><li>4× tblock-n2-minus</li></ul><h4>Sepiolite group</h4><ul><li>2× oblock-m8-plus</li><li>2× oblock-m8-minus</li><li>4× tblock-n3-plus</li><li>4× tblock-n3-minus</li></ul><h4>Kalifersite</h4><ul><li>4× oblock-m3-plus</li><li>4× tblock-n2-plus</li><li>4× tblock-n2-minus</li><li>4× oblock-m6-plus</li><li>4× tblock-n3-plus</li><li>4× tblock-n3-minus</li></ul><h4>Brucite group</h4><ul><li>4× oblock-m5-plus</li><li>2× single-octahedron</li><li>2× single-octahedron-clips</li><li>4× brucite-connector</li></ul><h4>Lizardite (kaolinite-serpentine group)</h4><ul><li>4× oblock-m5-plus</li><li>4× tblock-n2-plus</li><li>2× single-octahedron</li><li>2× single-octahedron-clips</li><li>4× lizardite-connector</li></ul><h4>Chlorite group</h4><ul><li>4× oblock-m5-plus</li><li>2× oblock-m5-minus</li><li>4× tblock-n2-plus</li><li>4× tblock-n2-minus</li><li>3× single-octahedron</li><li>3× single-octahedron-clips</li><li>4× chlorite-connector</li></ul>
