Knitting loom for a hat with interchangeable pegs. Grooves in the pegs to allow for crochet hook or weeding tool use. 

• Print 1x board and 42 pegs. 
• Recommend printing the pegs on their backs flat so the layer lines are perpendicular to the board when assembled.
• Print with supports for the loop on the side. 
• When assembling, the grooves on the pegs should face towards the outside of the circle.
