This development kit has two USB-C connectors without the pins soldered to the board. If your board has the pins already soldered, measure the length and change “Height_Pins” in the Fusion 360 model. The lid slides on the bottom and tolerances are snug; however, they may need to be adjusted for your printer. The internal length, width, and height can be tweaked with parameters. The buttons must be held up when sliding the lid on or off.
Supports were painted on some parts and printed with PETG:
Buttons - No support material is necessary.
Bottom - Support only for the USB holes so they do not collapse.
Top - Print face down with support only on the LED opening.
Insert - Support was used under the cross member. The part was printed right side up which used more material; however, it is easier to remove supports on the bottom. The bottom won't interfere with the top being slid on if there is any residual support material left after being removed.
No glue or extra hardware is needed to assemble the case.
Note: The ESP32 boards I purchased have a width of 28.10mm. The designed interior width of model is 28.3mm. @Boymeetsmill reported his recently purchased ESP32 boards have a 28.4mm width and did not fit properly in his printed model. You may want to measure your boards and scale the model ever so slightly to accommodate any manufacturing variance. This model was designed with a tight fit.
An alternate bottom STL file for developers was provided by Cinntu so it could be added to this posting for others to use.
