This is a giant knitting loom for chunky yarn that can be used for knitting blankets or large panels.  It will need to be assembled, and requires some machine screws to do so.  The pegs are replaceable, but are a press fit, and are a firmly in place.  I used a small rubber mallet to tap them into place.  They will required a small punch and hammer to drive them out. The .3mf file includes a tool to press the yarn down the peg to speed up the knitting process, a moveable peg if your design needs it, and a guard or 'block’ if to keep the knitter from creating a loop and accidently creating the worlds largest knitted tube.
