Wham Bam Flexible Build System for Prusa I3 MK3 or MK4 and similar. 254x235mm Magnetic Base and PEX surface plate. New in box, the open pictures taken are of my own that I am keeping, so that you can see what is included in the package. It will also come with two stickers, one of which is not shown because I used it, it just says "Ma'am" instead of "Man".The Magnetic Base may not be useful for the modern printers as most already have magnetic bases to my knowledge, but the PEX plate is certainly still useful. and usable.Shipping to Contiguous US 48 only! Sorry Alaskans and Hawaiians.
