6"L x 3.5"W x 2"H. Material is 1/8 Baltic Birch Plywood from Woodpeckers on Amazon. Their wood is, eh. Pretty warped. But bar magnets to hold it flat works wonders.
No masking. Used Proofgrade Medium Maple Plywood settings for cut and draft engrave. Everything but the base plate fit on one 12" x 12" sheet. 1 hour 10 minute run time. 20 minutes to assemble and glue.
