This is a 30cm knitting loom system I designed in Blender as a gift. It will print in place as one solid piece. Have a look at my print settings if you want to avoid layer delamination at the base of the pins.

I designed the pins to be as strong as possible with the constraint that I wanted to print this loom as one solid piece.

There is a little groove in each pins (excepted for the 2 end pins) allowing you to slide in your knitting hook in it.

Also considering the size of this loom it might be tricky to print it on your printer. I have printed it on my Alfawise U30 and the bed size is 22*22 cm. I had to place my model in diagonal in order to be able to print it.

You'll need to have a perfectly flat bed if you try to print this model and might need a raft. Personnaly I used a custom one, just for the end pins, included in the model because the one generated in cura would exceed the build area of my printer.
