Vertical box for Logic board & Raspberry Pi

cults3d

Box for Creality logic board (compatible with SKR Mini boards as well) + Raspberry Pi + slim microSD to SD adapter + 5VDC step down buck converter for Raspberry + 3x step down buck converters for fans. All in one box, cooled by 60 mm fan. I wanted to put all electronics in to one box and cooled by one middle size quiet fan. I also wanted to have easy access to the box, so I decided to use the same place/solution as Prusa use. In this case is necessary to extend horizontal profile 4040, because part of the box is over the original aluminum profile. The profile extender is prepared for my printer's tolerances so you may need to use the right tool (really biiig hammer :-)). El. connection between logic board and Raspberry is made by three internal wires (GPIO14, GPIO15 and GND) connected to proper pins on the SKR board. External USB cable isn't necessary. STEP files are included for all parts. Box is prepared for following hw: - Logic board compatible with the original Creality. SKR Mini E3 v2 in my case. - Raspberry Pi standard size (ie. except Zero). I am using Pi 3B+. - 5V Step down buck converter for Raspberry Pi https://www.ebay.com/itm/3-40V-3A-Step-Down-DC-to-DC-Voltage-Regulator-Module-Inverter-Power-Supply/283572698875?hash=item42063ffefb:g:RjYAAOSw46Fb2~Oy or https://www.gme.cz/napajeci-modul-3-40v-3a-step-down - SD card Female to TF micro SD Male https://www.aliexpress.com/item/4001203159338.html?spm=a2g0s.9042311.0.0.4bcd4c4dTuGgYx - Up to three pcs of Step Down Buck Converters for fans. https://www.ebay.com/itm/XL1509-Spannungsregler-2A-DC-DC-in-4-5-40V-out-1-27-37V-Step-Down-Buck-Converter/282268640167?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 or https://www.gme.cz/step-down-napajeci-modul-1-17v-2a-miniaturni - Noctua fan, type NF-A6x25 FLX. Is also necessary to replace original ribbon cable between board and LCD to the new one - longer. - 2pcs PFL10 connector for ribbon cable (cable between logic board and LCD) https://www.gme.cz/konektor-pfl10 - Ribbon cable, 10 wires AWG28 FBK10H https://www.gme.cz/fbk10h Screws / nuts: Logic board: 5pcs M3x4 ISO7380, you could use screws from original box. Raspberry: 3pcs M2,5x6 ISO7380/DIN912. Could be use longer. Cover: 6pcs M3x12 (up to 25) DIN912 with or without nuts. Both variants are possible. If you prefer nuts, you have to use longer screws (ca 20 or 25 mm). Box: 4pcs M4x10 DIN912 + T-nuts. 5V Step down converter: 2pcs M3x4 ISO7380. You can use for fixation of the MicroSD extender either attached SDclip model or heat both pins and "melt" them on the position. For better print quality all screws holes in the Cover (and also above the nuts holes in the main body) are covered by thin layer (0,24mm). For better understanding please look at Cover in your slicer (level +22 mm). Just use drill or proper screw driver to cut it off. And at the end, please excuse my poor English ;-)
