Flexy rex keychain

I made this to sell at my business. It's made to fit these keychain pieces https://www.amazon.com/dp/B08RHKRMWF?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

You can sell it too!!! I sell mine for $3.00 and they sell pretty well:)

I think that Bambu Labs keychain pieces will work, Please tell me if they do.
