If you want to use a D1 mini  with an USB-C port and no button you can print this remix instead: https://www.printables.com/model/836021-moon-rocket-700-stand-with-d1-mini-usb-c-holder

I decided to control the LEDs of the moon rocket I printed using an ESP32 D1 mini (https://www.az-delivery.de/fr/products/esp32-d1-mini) and needed a stand that could hold it and expose the USB port.

The design is made for the 700% scaled up version of the rocket so you'll need a bed of at least 20x20cm to print it.

The plume should fit directly into the top part of the stand (built-in clearance of 0.2mm) and can then be glued to it (but that's not a requirement)

The bottom part and feet can then be attached to the top part using M3 screws and heat set inserts.

The 3D printed button should be coated with a conductive material (or electroplated) and connected to one of the GPIOs pins of the ESP32 to control the LEDs. If the button moves too much you can use a longer M3 screw to stop it.

I also added the LEDs holder that I made. It takes 3x 5mm LEDs and has enough space in its central hole for 4x 22 AWG wires. In my case, each one of them is connected in serie with a resistor to a GPIO pin of the ESP32 (which allows to adjust their brightness and/or animate them independently). Here is a code snippet that can then be used to control them: https://gist.github.com/Lyrkan/59891d932db17d82d41ad3e4b35aedc2

Printing advices:

• Enable supports (you won't be needing a lot of them if the parts are printed in the right orientation)
• Infill is not required but you'll have to be careful how bridges are orientated so their lengths do not exceed the capabilities of your printer. I recommend adding some low infill or an adaptive one if you have any doubt.
• Make sure that seams are placed either at corners or in the back of the top part
• For the prints you can see in the pictures I:
  • processed the STL file in Blender to add some wood texturing (displace modifier)
  • printed the resulting model in an Eryone wood filament
  • lightly sanded the result
  • used wood stain on it
