A full set of looms, 4 circular loom sizes (XS-S-M-L, approx. 6cm-12cm-19cm-27cm internal diameter) + a customizable set for rectangular loom

Full size looms are available for download but only XS (maybe S, too) can be printed in once, that's why each of them is divided into pieces:
S and M circular looms and rectangular loom are divided into 4 pieces, L loom into 6

Just print the basic shape four times or add the final part with the horizontal peg to "lock" the yarn, useful but not essential
The pegs are designed to insert a 4mm size crochet and easily get the yarn loop

Each piece has 3 holes with 2mm diameter. you can use leftovers filament to join the pieces, a little glue will help keeping it all together and avoid disassembling while using it

INSTRUCTIONS
each file is named like this:

so if you see the file named

it's the L size loom and this file must be printed once
again, loom_SX3
it's the S size loom and this file must be printed three times

for the rectangular loom (named scarf loom) the file name is

BIG is the 6pegs piece and is supposed to be printed in pair
LTL is the 3pegs piece and is supposed to be printed in pair
U is the U shaped piece (short side of the loom) and, guess what? it is supposed to be printed in pair, too! =D
