Has anyone seen anything that allows for a small pump to be secured using the bottle cage screws but in a low profile? I see plenty of devices that allow for both the bottle cage and pump to be secured using the frame screws, but nothing that solely focuses on just the pump.

I run a single bottle only and want to leverage the second bottle location for a pump only and all the accessories I find try to accomplish both pushing the pump off to the side. Anything out there that simply mounts the pump to the bottle cage location parallel with the bike frame? (Like the bottle would be if used for a water bottle)
