Creality CR10 10S RaspberryPi Octoprint Holder with LED and build in step downs

thingiverse

What it is? The thing is the holder for Raspberry Pi for Craelity CR10V2 which should fit any printer with electronics box like this one. Fits normal CR10. It has place for two step downs – one for powering RPi (5V) and one for LEDs or anything (12V). Connections are designed with XT60 as input and output voltage. Lots of place inside, lid can have a different options as well as main body. Options For main housing: - With places for both of the step downs and RPi - With mountings only for RPi, can fir mechanical relay without a problem. For lid: - full roof: no place for anything (heatsink is a good option) - with Happy printing sign (heatsink is a good option) - 40mm fan edition (with hole for wires - 60mm fan edition (with hole for wires - Lid Mug Edition - for all of you who like to have dedicated mug stand for your coffee just above electronics while printing 10days long print for your boss. What can go wrong? Parts You will need: - One male and one female XT60, but of course you can wire them directly. Power is supplied from power supply which has plenty of extra 24V outputs. - two step downs, like this ones: <a href="https://botland.store/converters-step-down/17169-step-down-voltage-converter-d36v28f5-5v-32a-pololu-3782.html">here</a> and <a href="https://botland.store/converters-step-down/17175-step-down-voltage-converter-d36v28f12-12v-24a-pololu-3786.html">here</a>. They have this advantage that they have ENable pin which can be directly controlled by GPIO of RPi and Octoprint. - mechanical relay can be an option, I have made a main body variation without any mounting points for above step downs (see options section). - M3 screws, they are intended to got into plastic directly (up to 25mm in length). - M2.5x6mm screws for RPi and for my step downs are M2x8mm. - soldering iron recommended - RPi may be handy, I used RPi 3B+ but it should fit any other. microUSB port is not so accessible so or you have flexible right angle cable to power it up, or use GPIO directly. I went the this other way because the step downs are of a very good quality. Assembly Not that hard in my opinion. I think it's pretty easy but if you have any questions DM me or write a comment :) Updates <blockquote> 23/05/2021 initial release</blockquote> Sources <blockquote> -Steps ups and downs (like square signal does) models <a href="https://botland.store/converters-step-down/17169-step-down-voltage-converter-d36v28f5-5v-32a-pololu-3782.html">from here</a> <a href="https://botland.store/converters-step-down/17175-step-down-voltage-converter-d36v28f12-12v-24a-pololu-3786.html">from here</a> </blockquote> <blockquote> -Cup 42 model <a href="https://grabcad.com/library/cup_42-1">from here</a> </blockquote> <blockquote> -XT60 model <a href="https://grabcad.com/library/xt60-male-genuine-and-xt60-female-genuine-1">from here</a> </blockquote> <blockquote> -Raspberry Pi 3 model <a href="https://grabcad.com/library/raspberry-pi-3-model-b-reference-design-solidworks-cad-raspberry-pi-raspberrypi-rpi-1">from here</a> </blockquote>
