Don't settle for the recommended 25mm circular needle (US U) to make that Jumbo 7 threaded cozy blanket! Grab a 1.5" PVC pipe and go for broke!
Take PVC pipe, cut one end vertically and the other end at 45 degrees. Print out a pair of these attachments and then link them together with either a 5/8" tube or a rope of similar diameter.
The interconnecting tube (or rope) needs to have an ID of about 16.3mm. My 5/8" tube fits inside snugly enough to not require any glue.
A 1.5" PVC pipe is going to have an OD of 48mm (even though 1.5" is closer to 38.1mm). Make a note of it :)
The end result should be single print.. no support necessary.
If you found this useful, it would bring me great joy to see your work - so be sure to share. :)
