Mind this is worth the two pence offered but here goes:
For such a basic shape common to most drilling-boring designs, that being a cylinder with some sort of auger-tipped 'nose cone', I can see many easily had items to make such a machine from scratch.
A great place to start would be simply looking at the textured or often ridged-ripples plastic one (1) liter bottles that soda, tea and water are commonly packaged. Right off, the twisted fluting on a Pepsi bottle might be a place to start.
Again, perhaps browse your local dollar-thrift store, especially in the kitchenware aisles as well as gardening-floral design supplies of a dedicated craft shop.
May sound like a bit of effort but trust me, a vehicle of your own design and construction brings not only comments-compliments but a sense of satisfaction to the builder.
Good Hunting !
