A rant to begin: Photography accessories are truly odd. It's supposed to be a Bowens mount, yet you just can't fit it in. It's supposed to be a mini Bowens mount, yet once inserted, it just doesn't hold firmly

There's clearly a standard, yet every manufacturer uses wildly different sizes. It's truly incomprehensible [what a rip-off]

To enable my old Ulanzi COB40W fill light to use Bowens mount accessories, after purchasing an adapter online that didn't fit and returning it, I decided to make one myself

About the Adapter:

UPDATE:2025.9.3

1.Modified appearance [Looks better?]

2.Adjusted Bowens mount dimensions [Tighter fit]

3.Adjusted print orientation and some print settings [Faster print time, easier support removal]

Negative parts were added to the mini Bowens mount to make the buckle size suitable for the Ulanzi COB40W (non-pro). With appropriate modification or deletion, it should be adaptable to other mini Bowens mounts (I don't have other mini mount devices unfortunately)
Please use high-temperature resistant filament. If you need increased durability, please adjust the number of walls and infill as needed
PS. This is only for simple adaptation. For professional shooting or high-load accessory adaptation, please use with discretion
Please measure the interface values of your equipment in advance. If there's a significant difference, please adjust the model size to fit

If this helps you, please treat me to some bamboo poop
