Like a few had posted, I always just propped up something when i needed a clean backdrop, usually 2mm light blue foam, but after a couple weeks pondering the posted ideas on homemade profile plates the mental wheels wouldn’t leave it alone. Not only a profile plate, but also the problem on how to connect it to the vise. This is what I came up with.

Cardboard back cover of notebook (not shown): free (but I’m sure I’ll hear about from one of my kids one of these days).
Hardwood block rough cut to 5/8" x 5/8" x 2". Block shown is a Wenge pen blank I had on hand from another project.
Total cost less than $7
Tools needed:
Drill (Drill press preferably) and various drill bits.
Fine kerf saw (2" dremel saw if available)
Tap & Die set for cutting threads in brass and aluminum
Sandpaper
Epoxy
Flat paint (any color). Plaid? brand craft paint is cheap and available in any craft dept.
Fabrication directions:
Hoop:
Remove center ring from embroidery hoop and slice in half to make two smaller hoops. The idea was that even a fine kerf blade would leave enough of a gap for cardboard substrate and 2 layers of card stock.
Sand lightly all surfaces of now 3 rings. Paint as desired.
Support rod:
Cut threads with thread die on each end of brass rod.
Tap matching threads in aluminum spacer.
Bend brass rod 90deg approx 4" from one end.
Epoxy threaded aluminum on outside of hoop opposite tension screw.
Block:
Drill a 3/8" through hole 3/4" from one end of hardwood block. Assuming vise stem is 3/8".
Drill a 5/32" through hole 5/8" from the other end of block.
Roll the block 90 degrees onto adjacent side and drill a 5/32" through hole that bisects first 5/32" hole.
Use countersink bit to slightly flare through holes.
Drill pilot holes (to threaded insert mfg specs) in each end. This is where drill press really helps.
Sand all sides and finish as desired.
Screw in threaded inserts in end holes. Insert cap screws in ends.
Profile inserts disc’s:
Use one of the inner rings and trace outside diameter on cardboard and card stock. Cut out disc’s. Sandwich one inner ring, card stock, cardboard, other card stock and other inner ring and insert in outer hoop. Tighten hoop to secure inner rings. Thread on brass rod and mount in vise block. Plate will swing around to use either side, you 'll just need to adjust brass rod to fit behind vise jaws.
