There are three ways to use the BabyMotion Flanges with Spectra pumps. We recommend hack 2 over hack 1 and 3 for ease of use.
If you have Medela connectors and bottles and wish to use them, you can purchase a Medela to Spectra adaptor (yellow piece) and set up like below (Hack 1).

If you have no Medela parts and wish to use Spectra bottles, you can purchase this Spectra adapter and set up like below (Hack 2).

If you don't want to buy additional parts, you can also use this DIY hack (may not work for Spectra 27mm flange). Credit: Emma Mokler
