This is for the Bowflex 552 series 1 dumbbell set (red numbers on dial)

I printed these out of abs and installed pins for added strength, these are push fit no need to heat them.

Pin size is 1mmx5mm, I sourced them from amazon.

You will need 6 pins for each plate.

In the prints profile I used petg as an interface material, and it makes the supports pretty easy to remove.

Thank you for checking them out and let me know how they work if you print one!
