The connected PDF (CNC-Part-Summary.pdf) offers detailed price and sourcing info for each required half. Listed right here is simply a abstract

Sheet Stock — $20
-a 48″ x 48″ piece of half” thick MDF (any half” sheet inventory can be utilized I’ve plans to make my subsequent model out of UHMW however price was prohibitive this time round)
