Although printed PETG (or similar materials) does not match the structural rigidity of aluminum, it remains perfectly suited to this type of open-air enclosure, where mechanical stresses remain low and stability depends mainly on the overall design of the chassis rather than extreme load resistance.<\/p>\n<p>Once assembled, the structure offers excellent rigidity for everyday PC use, including gaming and workstations.<\/p>\n<p>All you need are M4 \u00d7 10 mm screws: all holes, threads and anchoring points are dimensioned for reliable M4 fastening.<br \/>\nM4 is the best compromise between M3 and M5, works perfectly with 2020 profiles and prints cleanly with a standard 0.4 mm nozzle.<\/p>\n<hr \/>\n<h4>Scalable and modifiable<\/h4>\n<p>With the 3D files supplied, you can easily adapt or enlarge the chassis for other motherboard formats (ITX, ATX) or even reuse certain parts for DIY 3D printer enhancements or other custom projects.<\/p>\n<p>The 23 cm 2020 profiles shown in the photos correspond to the practical height limit (Z axis) for most 3D printers with 230 \u00d7 230 mm platens.<br \/>\nCoincidentally, 23 cm is exactly the length needed for a mATX motherboard format.<\/p>\n<hr \/>\n<h4><strong>Why \u20ac19.90 is a bargain<\/strong><\/h4>\n<p><strong>This STL package lets you build a fully functional mATX open-air PC case with 12 fully 3D printable parts.<\/strong><\/p>\n<p>Consider this:<\/p>\n<ul>\n<li>A comparable mATX open-air PC case generally costs between \u20ac35 and \u20ac100.<\/li>\n<li>With this package, you save money and shipping costs, while retaining total control over materials, colors and printing parameters.<\/li>\n<li>The design is modular, optimized for maximum airflow, and fully compatible with 3D-printed 2020 (or aluminum) profiles.<\/li>\n<li>You receive 12 ready-to-print parts, designed by Apiobi, including supports for GPU, power supply, storage and power button.<\/li>\n<li>Once you have the files, you can print as many cases as you like, for your own personal use.<\/li>\n<\/ul>\n<p>For \u20ac19.90, you get a fully customizable premium PC case experience, for a fraction of the price of a physical product.<br \/>\nPerfect for makers, gamers and DIY enthusiasts who want a unique configuration.<\/p>\n<hr \/>\n<h4>Parts included<\/h4>\n<p><strong>You're about to download no fewer than 12 components, all optimized for strength, printability and ease of assembly:<\/strong><\/p>\n<ul>\n<li>Profile 2020 \u00abaluminum type\u00bb (standard geometry, printable; supplied as a 10 mm segment to be resized in Z in your slicer)<\/li>\n<li>Cross-junction plate - T<\/li>\n<li>90\u00b0 square with 4 holes<\/li>\n<li>2-hole 90\u00b0 bracket<\/li>\n<li>GPU bracket holder<\/li>\n<li>Handle<\/li>\n<li>Mounting bracket for mini power button (see photo of button model)<\/li>\n<li>Mounting bracket for 2 \u00d7 2.5\u2033 disks<\/li>\n<li>Power supply mounting bracket (PSU bracket)<\/li>\n<li>End cap for profile 2020<\/li>\n<li>M4 nut for T-slot<\/li>\n<li>T-slot spacer nut for motherboard mounting<\/li>\n<\/ul>\n<hr \/>\n<h4>Design choices and voluntary limitations<\/h4>\n<p><strong>Creating a fully 3D printable PC case required certain compromises.<\/strong><br \/>\n<strong>This model includes everything needed for standard gaming or workstation configurations, but I've deliberately chosen not to design some of the more specialized accessories.<\/strong><\/p>\n<p>For example:<\/p>\n<ul>\n<li>Dedicated support for cooling modules<\/li>\n<li>Advanced GPU support system<\/li>\n<li>A wide range of customized spacers (various lengths and shapes)<\/li>\n<li>Various mounting options for power buttons (reset, LED HDD, etc.)<\/li>\n<\/ul>\n<p>These additions would have added considerably to the complexity, without serving the main objective: to offer a robust, functional, uncluttered and fully 3D printable base, covering standard needs while remaining simple to print, assemble and modify.<\/p>\n<hr \/>\n<h4>The story behind the project<\/h4>\n<p><strong>Tired of traditional closed PC cases, I first used these parts to build a compact 1080p steambox PC (visible in the photos). Encouraged by the result, I then rebuilt my professional workstation using the same system, making it much more portable.<\/strong><\/p>\n<p>My next configuration is already planned: an open-air chassis dedicated to retro-gaming, with a focus on classic arcade games.<\/p>\n<p>If you're reading this, you probably have your own project in mind.<\/p>\n<p>Have fun building a machine that reflects your style - and feel free to share photos of your creation.<br \/>\nI'd love to see what you come up with.<\/p>","protected":false},"excerpt":{"rendered":"<p>Build your own open-air PC case with fully 3D-printable structural elements, including 2020 T-slot profiles<\/p>","protected":false},"featured_media":991,"comment_status":"open","ping_status":"closed","template":"","meta":{"_themeisle_gutenberg_block_has_review":false},"product_brand":[302],"product_cat":[130,146],"product_tag":[692,711,713,208,715,699,700,705,690,708,689,697,684,695,685,714,712,686,693,683,716,702,698],"class_list":["post-987","product","type-product","status-publish","has-post-thumbnail","product_brand-apiobi","product_cat-modeles-3d","product_cat-technologie","product_tag-2020-t-slot","product_tag-boitier","product_tag-chassis","product_tag-diy","product_tag-equerre","product_tag-gamer","product_tag-gaming","product_tag-geforce","product_tag-gpu-mount","product_tag-gygabite","product_tag-high-airflow","product_tag-hobbyist","product_tag-matx","product_tag-open-frame","product_tag-open-air","product_tag-ouvert","product_tag-pc","product_tag-pc-case","product_tag-pc-modding","product_tag-piece-detachee","product_tag-profile-2020","product_tag-radeon","product_tag-workstation","first","instock","featured","downloadable","virtual","sold-individually","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/product\/987","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/comments?post=987"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/media\/991"}],"wp:attachment":[{"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/media?parent=987"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/product_brand?post=987"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/product_cat?post=987"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/apiobi.com\/en\/wp-json\/wp\/v2\/product_tag?post=987"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
