DC-DC LM2596 Buck Converter Case. Inc creality cr20 mount

thingiverse

The primary objective of this project is to minimize accidental shorts, provide protection for pins, and make mounting the PCB effortless. The case accommodates PCB boards that snap into place inside it, offering two mounting holes or tabs specifically designed for the Creality CR-20 printer. It's possible that other printers may also be compatible, but I'm unsure which ones. The extruded aluminum attachment is approximately 40mmx40mm in size. In normal mount mode: I've used 5mm diameter #8 wood screws for the holes. Although I haven't printed or utilized this particular case as of my last update, the main section mirrors that of the CR-20 mode, which I have previously used. In CR-20 printer mount mode: No screws are required for installation; instead, the case is held slightly off the ground to allow for airflow. Inserting it into the channels can be a bit tricky, but holding onto the base rather than the small end walls makes the process smoother. This design serves a specific purpose - housing DC-DC converters that can be found online, such as those featuring the LM2596 module on eBay. Searching for "lm2596" will yield results like this one: https://www.ebay.ca/itm/DC-DC-3A-adjustable-buck-module-LM2596-regulated-24V-to-12V-5V-3V/132970089457?hash=item1ef5a28bf1:g:sSEAAOSwNpRb0zQM:rk:1:pf:0 These converters work exceptionally well with my collection of Atmel ATmega128A microcontrollers. The design was created using Freecad, and both the Freecad files and STL files are included for users to test and experiment with. Print Settings: As every printer and material combination is unique, I've listed my initial attempt's settings. Feel free to improve upon them as needed (100mm/s print speed, 0.4mm nozzle size, 0.2mm layer height, 115% feed rate, etc.). Notes: * To prevent overheating issues with the PCB boards, I've kept plastic away from heat sources and ensured adequate breathing room. * The added heat sink is intended to accommodate a Raspberry Pi 3A+ and other components that will be connected to it. * Due to limitations in Freecad's naming conventions, this design may not be as polished as my previous creations. I'm still working on finding solutions for these issues (referencing constraints).
