Endoscope tip accessory device with dimension variability compensation

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.
