colorFabb PETG Economy is an option for those looking to maintain the high quality standards that colorFabb adheres to at a bit of a bargain per kg. The economy PETG is provided on large spools and in large quantities of 2.2kg so that you get more value per kilogram out of your purchase.
PETG is a great functional material. If you're an ABS user, give this a try and you may find that you are a convert.
Note that the spool size is much larger than can fit on nearly any standard printer spool holder. So, you will need to print one. OD is 300mm, Bore is 52mm, and width is 102mm. ColorFabb has shared their design for a spool holder here.
