This was one of the first things I 3d printed, which I only started getting into a month or so ago. I've had a lot of problems since with excessive stringing and filament constantly oozing out of the nozzzle which have been super frustrating, no amount of tweaking settings is fixing it, but at least I got this really wonderful model from Loubie to print right. Sending it to my niece in Germany, hopefully she'll love it.
I used 6 mm magnets from home depot for the head/hook, be careful to set them with the right polarity I also ran armature wire through it with the suggested elastic cord to counteract the elastic pulling the limbs and joints tight and so it could keep its pose better. I did print with supports for certain things like the ears and the head. It is designed without supports needed but it was one of the first things I printed and I was concerned about overhangs and prints falling over during the print. I didn't need a raft or adhesive on the bed but I did use a small brim to help with that first layer adhesion.
I can't say enough how much I love this model, Loubie put together a really excellent design which I'm sure took a lot of work and tweaking to get everything to fit just right.
Oh one last thing, for the eyes, I used 10mm eyes that I bought from Amazon, I would suggest using some type of putty to stick them in place from the inside of the head. I used crazy glue and it is incredibly difficult to set them in place and not get the glue on the glossy part of the eye, all it takes is the slightest bit to run to ruin them and no matter how careful you are there is not a lot of room inside the head to set them in place and rotated correctly so it doesn't look cross eyed, unless you get super lucky you will need to re-position them after getting them into the socket and that tiny bit of movement will get some of the crazy glue on there. Even if you get the type that says it dries clear, it wont be completely transparent or even necessarily smooth once dried. Don't get lazy and use a glue, save yourself the trouble, don't do it, get some putty or something to stick them in place from the inside.
