Description
Description
When boondocking in my RV, my Starlink connection would frequently drop out. As the RV battery voltage sagged—especially when loads like the water pump or furnace kicked in—the voltage supplied to Starlink would dip enough to cause a shutdown.
The solution was a 12 V to 20 V DC buck/boost converter to maintain a stable supply voltage. To make this reliable and portable, I designed a rugged, watertight enclosure to house the converter, provide easy plug-in access for the Starlink cables, and include LED power indicators.
The enclosure is designed to be strong, weather-resistant, and easy to print.
Printing Notes
- No supports required
- Printed with 3 walls and gyroid infill for strength
- An optional TPU gasket can be added for improved sealing
- Printed in PETG due to heat concerns, though heat has not been an issue
→ PLA should also work fine
