A system for reversibly mounting an object, the system comprising a base having a first region and a second region in rotatable communication with the first region such that in a first configuration, the regions are not coplanar and in a second configuration they are. Also provided is a system for removably mounting objects, the system comprising a base having a first end defining a first cross section; and a lever having a second end defining a second cross section, the lever in rotatable communication with the base such that in a first configuration, the ends are not aligned, and in a second configuration the lever is nested within the base such that the ends are aligned to form a continuous geometric shape defining an aperture adapted to receive a carrier.
