I designed this fitting with the following goals:
Easy to carry essential pump parts, and the parts should fit snugly/securely;
Avoid dangling tubing whether or not the flange & bottle is in use (support mounting the back-flow protectors alone);
Reduce air exposure of flange / breast shield interiors;
Works with any bottle that your flange supports (e.g. in addition to spectra bottles, we occasionally pump into a Dr. Brown bottle using an adapter for the flange);
Keeps center of mass close to that of the pump itself.
The gap in the centerpiece is for mounting the back-flow protectors alone (without breast shield).
Attached is also the OpenSCAD model where I roughly reproduce the S1+ pump itself and bottle/flange/back-flow protector — in addition to the actual fitting itself and different scenarios of how it fits.
Assembly: there are four pieces, three of which are to be glued into matching inserts on the cylindrical base.
Fit: (a) There may be different dimensions on your S1+. To verify fit, the cupholder should fit a 2.5" diameter cylinder. (b) Tested with the back-flow protector, 24mm and 28mm flanges that came with the pump, and tested with off-brand 21mm flanges and it probably works with other brands/sizes; you're welcome to modify the OpenSCAD program for your specification of flange to verify/adjust for your needs.
