This time, we will take on the challenge of creating a custom case to house this system. In particular, we&#8217;ll introduce the final form where a model was designed using FreeCAD, printed with a 3D printer, and integrated with the Raspberry Pi 3 and Pico.<\/p>\n<h2 class=\"\">Model Design with FreeCAD<\/h2>\n<p class=\"\">The case was designed using FreeCAD, focusing on the following points:<\/p>\n<ul>\n<li class=\"\">\n<p class=\"\"><strong>Raspberry Pi 3 Mounting<\/strong><br \/>\nThe mounting position and dimensions for the Raspberry Pi 3 were accurately identified by referencing the <a class=\"\" href=\"https:\/\/www.raspberrypi-spy.co.uk\/2012\/11\/raspberry-pi-mounting-hole-positions-and-template\/\" target=\"_new\" rel=\"noopener\">Mounting Hole image from Raspberry Pi Spy<\/a>.

Because this project is intended for monitoring an ASRock Beebox and does not require a PS\/2 keyboard or mouse connection, the implementation is delightfully simple.<br \/>\n<a href=\"https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793.jpg\"><img decoding=\"async\" class=\"aligncenter size-large wp-image-1236\" src=\"https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-1024x783.jpg\" alt=\"PiKVM (Raspberry pi 3 + pico + hdmiusb)\" width=\"1024\" height=\"783\" srcset=\"https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-1024x783.jpg 1024w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-300x229.jpg 300w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-768x587.jpg 768w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-1536x1174.jpg 1536w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-530x405.jpg 530w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-565x432.jpg 565w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-710x543.jpg 710w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793-725x554.jpg 725w, https:\/\/donguri3.net\/wp-content\/uploads\/2025\/04\/IMG_16471-scaled-e1743981116793.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/p>\n<p class=\"\">Additionally, we intentionally designed the case without a lid, exposing the internal electronic circuits and boards to give it an authentic &#8220;maker&#8221; aesthetic. This design emphasizes a DIY vibe and technical appeal.<\/p>\n<h2 class=\"\">Conclusion<\/h2>\n<p class=\"\">The case designed in FreeCAD and printed with a 3D printer was built and processed based on the precise mounting positions of the Raspberry Pi 3 (<a class=\"\" href=\"https:\/\/www.raspberrypi-spy.co.uk\/2012\/11\/raspberry-pi-mounting-hole-positions-and-template\/\" target=\"_new\" rel=\"noopener\">reference site<\/a>) and the actual dimensions of the Pico clone. The finished case is simple yet securely holds the internal components in place, and leaving the lid off creates a wonderful DIY look. Next time, we will put this completed system into action and introduce the verification of its monitoring functions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the previous hardware and software editions, we built a PiKVM using a Raspberry Pi 3, a Pico clone, and an  [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":1318,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_locale":"en_US","_original_post":"https:\/\/donguri3.net\/?p=1140","footnotes":""},"categories":[1164],"tags":[327,9,463,461,462,1153,275,278],"class_list":["post-5030","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-diy-tools-devices","tag-3d","tag-diy","tag-pico","tag-pikvm","tag-raspberry-pi-3","tag-usb","tag-275","tag-278","en-US"],"_links":{"self":[{"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/posts\/5030","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/comments?post=5030"}],"version-history":[{"count":1,"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/posts\/5030\/revisions"}],"predecessor-version":[{"id":5033,"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/posts\/5030\/revisions\/5033"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/media\/1318"}],"wp:attachment":[{"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/media?parent=5030"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/categories?post=5030"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/donguri3.net\/wp-json\/wp\/v2\/tags?post=5030"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
