Double DC/DC Buck-Converter Base-Plate holder for Prusa Mini

prusaprinters

<p>This is a simple base which holds two DC/DC converters from Amazon/Ebay. I use these to step down from 24V to 12V for my LEDs and 24V to 5V for my Raspberry Pi. I quite like to look at the electronics (but not at the cables) so I have not designed a cover for the Converters.</p><p> </p><p>The regulators I use: Pemenol LM2596 DC/DC Converer (<a href="https://www.amazon.com/dp/B07MMQ8KG8/ref=cm_sw_em_r_mt_dp_XNZH9GWFNB4T0BT3RB1X">Amazon.com</a>, <a href="https://www.amazon.de/dp/B07MMQ8KG8/ref=cm_sw_em_r_mt_dp_QQDC2GX3PA35VZ7PFFAE?_encoding=UTF8&amp;psc=1">Amazon.de</a>)</p><p>The bord/drill dimensions for anyone curious: 26mm x 49mm, the two holes form a rectangle of 23.2mm x 33 mm</p><p> </p><p>The mounting hole to screw on the plate is sized to fit the M4x16 screws I had laying around.</p><p>For mounting the DC/DC Converters I chose to try out brass inserts for the first time, the holes are therefore dimensioned with a diameter of 4mm.</p><p>The T-Nut I chose: <a href="https://www.prusaprinters.org/prints/42971-t-nut-for-pursa-mini-extrusions-groove-8-type-b-m4">T-nut for Pursa Mini extrusions (groove 8, type B, M4 thread)</a></p><p> </p><p>By powering everything directly from the buddy board I can directly switch on the 3D Mini, the Raspberry with the Camera and the LED Lights just by flicking the one built in switch of the Prusa Mini.</p>
