Hardware:

• For the bottom part: M2 machine screws with 6-8mm length
• For the top part I used self tapping M2.3 screws with 6mm length

Print settings:

• Use supports for the overhang
• I used PETG for the added heat resistance

Notes:

• I recommend using the external antenna for elrs and adding an additional internal one for the cc2500.
• Wire the ELRS module to the pins for the external module bay.
• Don't forget to limit the power to 100mw, to prevent overheating or add a fan.
• Use a small amount of hot glue or similar, to prevent strain from moving the antenna from pulling on the connector.
• The case can be closed afterwards without interference.
