Ender 3 Pro Brain Case - MKS Gen L + Raspberry Pi 3 B

thingiverse

Box designed for Raspberry Pi and MKS Gen L on Ender 3 Pro. Ports are located at front for easy access, boxes mate with dove tails. Suggestions and feedback welcome! If you like this design consider clicking that "Tip Designer" button! To do: - Remove dovetails? - Cable path for screen, Z limit, pi power/ethernet - Fan placement - Raspberry Pi power button (using OnOff Shim) - SD slot - Indicator lights Printed left side at .32 with no supports and came out great. Had stepper driver mishap necessitated upgrade to MKS Gen L before ready. All mechanical pieces for Ender 3 available via github, really helped in designing this. Update 2019-02-13: Added hinged lids. Hinge will slide forward in track so lids can be pivoted up, clearing bed. Used pair of nails for pins in hinges. May need light sanding to get parts to mate if over extrude. Hole pattern for 5015 radial blower on Pi lid, placed fan to blow across stepper drivers. Render shows 2 relay board, but no mounting points. Fits there nicely though. Update 2019-02-08: Right side adjusted by 1mm, now includes Rpi studs and ports. Added externally accessible tray in unused portion. Lids are work in progress. Connected Serial on Rpi directly to D0, D1 on MKS Gen L, along with ground so they would be common. To enable serial on pi, go to raspi-config and set it in communications menu. Serial port will be /dev/ttyS0 for pins 8(TX) and 10(RX). The serial pins are available on AUX1 header as D0(RX) and D1(TX), mislabeled as D1 and D2 on some pinouts. Keep in mind TX (transmit) should connect to opposite RX (receive). Will probably add versions without dovetails so it is easier to move trays independently.
