The endoscope accessory assembly may comprise an accessory device comprising a first base, a plurality of flexible struts, and webbing connecting each of the flexible struts. The accessory device is configured to receive a distal end of an endoscope. The endoscope accessory assembly may further comprise a dimension-compensating component comprising a second base, a plurality of flexible arms extending radially out from the second base, and at least one chamber at a distal end of the flexible arms. The accessory device is configured to be over-molded onto the dimension-compensating component in order to form the endoscope accessory assembly. ## Claims ### Claim 1 An endoscope accessory assembly, comprising: an accessory device, further comprising: a first base having a first inner surface dimensioned to receive a distal end of an endoscope, a plurality of flexible struts extending radially out from the first base in a first direction, and webbing connecting each of the flexible struts and configured to form a collapsible umbrella; a dimension-compensating component, further comprising: a second base having a second inner surface dimensioned to receive at least a portion of an outer surface of the first base, a plurality of flexible arms extending radially out from the second base in a second direction opposite the first direction, and at least one projection extending radially inward at a distal end of the arms, wherein the accessory device is over-molded onto the dimension-compensating component such that the first base of the accessory device completely encapsulates the plurality of flexible arms of the dimension-compensating component while the second base is exposed. ### Claim 2 (depends on 1) The endoscope accessory assembly of claim 1, wherein at least one of the first base or the second base is triangular, rectangular, or cylindrical in shape. ### Claim 3 (depends on 1) The endoscope accessory assembly of claim 1, wherein the at least one projection is configured to stop the distal end of the endoscope from extending beyond the distal end of the arms. ### Claim 4 (depends on 1) The endoscope accessory assembly of claim 1, wherein an inner diameter at a distal end of the arms is less than an outer diameter of the distal end of the endoscope. ### Claim 5 (depends on 1) The endoscope accessory assembly of claim 1, wherein the flexible arms deform inward at rest such that an inner diameter of the second base is greater than an inner diameter at the distal end of the arms. ### Claim 6 (depends on 5) The endoscope accessory assembly of claim 5, wherein: the plurality of flexible arms is configured to deform outward when the accessory device receives the distal end of the endoscope; and the plurality of flexible arms is configured to generate a force inward onto the distal end of the endoscope. ### Claim 7 (depends on 1) The endoscope accessory assembly of claim 1, wherein an inner diameter of the first base remains constant. ### Claim 8 (depends on 1) The endoscope accessory assembly of claim 1, wherein: the dimension-compensating component is made of plastic, and the accessory device is made of silicone. ### Claim 9 (depends on 1) The endoscope accessory assembly of claim 1, wherein the first inner surface of the accessory device comprises at least one crush rib. ### Claim 10 (depends on 1) The endoscope accessory assembly of claim 1, further comprising an extension cup coupled to the distal end of the flexible arms such that, when the accessory device is over-molded onto the dimension-compensating component, the extension cup extends beyond a distal end of the first base. ### Claim 11 (depends on 10) The endoscope accessory assembly of claim 10, wherein the extension cup further comprises: a third base; and a second plurality of flexible arms configured to couple to the distal end of the flexible arms of the dimension-compensating component. ### Claim 12 (depends on 11) The endoscope accessory assembly of claim 11, wherein a distal end of the third base is tilted at an angle along a vertical axis.
