Disclaimer: If you damage any device using this print, it is your responsibility to repair or replace it at your own cost. Before connecting wires and power supply, verify the polarity of your device's positive (+) and negative (-) terminals. If you have a device powered by 4x AA batteries placed next to a power outlet, consider using a 6V DC adapter for a convenient solution. Our SureFlap cat flap requires frequent battery replacements every three months, which can be expensive. Additionally, dead batteries may prevent our cat from entering or exiting the house. To address this issue, I designed an adapter that utilizes a 6V DC power supply to replace AA batteries. This adapter should work with most devices powered by 4x AA batteries. When assembling the adapter, note that it has a tight fit. Be cautious when inserting the M4 bolts and ensure the flat side of the print faces upwards. Verify the battery compartment's positive (+) terminal and check the polarity to avoid damaging your device. To accommodate the power supply wires, you can create a hole in the battery cover. Required materials include: Two M4 bolts (10mm long) Two M4 nuts 6V DC power supply Wires
