Description
I designed this adapter out of necessity.
I had a softbox with a round mounting plate secured by four screws, but all my lights use a Bowens mount. Instead of replacing the softbox, I decided to design and print an adapter that makes both systems work together.
This adapter converts a round 4-screw softbox mount to a standard Bowens connection.
It allows you to keep using existing gear without buying a completely new setup.
It’s a straightforward, functional design made to solve a real problem — no unnecessary extras, just what’s needed to make it fit and hold securely.
Designed for softboxes with a round plate and four mounting screws
Converts to Bowens mount
Printed in a strong material for durability
Make sure to use sufficient infill and a sturdy filament
If you’re in the same situation — having good gear that just doesn’t match — this might save you some money and frustration.
