Tony,
I hope this helps you out.
Try fashioning something from white PVC irrigation pipe and or the PVC fittings. Nylon cable or plastic garden ties also help. PVC pipe is easy to work and cut and join with the relevant glue. It can be re-shaped quite easily if needed by heating it up. I boil up water and put it into the hot water so as it does not burn or catch fire, retrieve the piece form the water with a pair of barbecue tongs(steak tongs)then hold with my hands using some heavy duty welding gloves. Soon as I achieve the shape I want I just dunk the hot piece into cold water. Sets, the desired shape permanently. Can be painted and co constructed with many other materials like wood aluminum other plastics.
Eg: Make a full lenth scarab or cut two rings off the end of a length of a 25 mm diameter PVC pipe or PVC fittings that are about 1 inch long. Expand them with heat to suit. Glue them to each end of a piece of flattened and the same diameter PVC pipe (or a flat piece of anything sturdy and about the same length of the probe. This you can Velcro , double sided tape or even tie on with electrical tape or cable ties on the body of the Explorer
