  • I have a few ideas -

    1. Replace the posts with wooden dowels. That might make it stronger and still cheaper.
    2. This one is harder to describe. Assume that you have a post of diameter 5mm and length 100mm, and your base is 20mm high. At the post’s base make it dia 10mm and height 10mm. Now make a similar negative feature in your base ⌀5x10, ⌀10x10. To assemble, insert the post from the bottom of the base. This way you’ll get a lot more support.
    3. You can make the idea above more 3d printable by using generous chamfers.
    4. Your current profile is hexagonal, you can still make the collar. Make one of the edges coincident instead of the axis. You’ll still be able to print flat. Or if you want a concentric hexagon then cut off the excess collar at the plane of the shorter hexagon.
    5. You can employ a similar technique for the top but you’ll have to get more creative there.

    (Edit - I’m sorry, I can’t figure out formatting on my app)







  • Thanks. These tips help a lot.

    I wouldn’t say that the goal is to learn. I have implemented the design on a Dev board. I also designed a breakout board which worked well. I am now considering just trying to do a new layout in a smaller form factor.

    There are bigger system integration tasks that I need to address before I can spend my resources on learning ESP32’s board layout. That is why I wanted to derisk my design by building on top of a known good design or at least find out the best practices of board layout.


  • My goal is to make a dev board with a custom layout. So if I can use ESP32-DevKitC as a starting point then I can focus on the board layout having some confidence that the component selection and the routing is done correctly. That’ll have save me some design iterations.

    Maybe you are right that it is simple enough to recreate it and I just need to give it a try.
