DIY swift ultra cheap
two wire coat hangers
Straighten out the hangers w/pliers, tape to the susan, bend arms upwards. Easy peasy.
I looted the susan from my kitchen; cost me $2 originally. Hangers, duct tape and pliers are ubiquitous. If you don't have something, you can probably borrow from a neighbor.
If the ends of the wire snag, you could slip a piece of aquarium tubing over them, wrap with some masking tape or dip in that plastic dip sold for tool handles.
