Initially, we wanted to kill this print, but it worked well in the end. Later we learned, that it happens quite often, that the shell gets detached from the printing bed in the process.

We also made 2 min video:

The shell is waaay too thin at the bottom. I had to thicken it in Blender (boy, that mesh is ugly). I didn't want to mess with the mesh too much but ideally I would just add a little foot at the bottom (perhaps 0.4mm tall, or 0.6, but I suspect that even 0.2 would work - and 5mm wide).

Don't forget your fan during the hairy lion print.
I only leave the fan off during the first three layers, then turn it on for the remainder of the print

That could be very helpful. In our opinion, if you load this item with an improved shell as the remix, it could help other makers a lot. Someone on Facebook recommended to use a raft to avoid this issue. But a raft could damage the item's base, which otherwise is ideally smooth.

The fan worked fine during this print. The problem was a poor adhesion to the printing bed that failed to hold due to a very thin shell. The bed temperature was 100 C plus an extra strong Pritt glue stick.

OK, my bad
Just looked like your fan was off in the photo you uploaded
I did not have any problems with any of the three lions I've printed.

You do know they have created one that has a brim around the support piece. It was uploaded to Thingiverse 2 weeks ago.

I hadn't noticed the version with brim in there - very definitely recommended if you don't want to waste time and filament.

My version is not worth uploading as it was a quick hack and will definitely waste too much time/filament compared to a proper solution.

Forgive me for stating the obvious, but why don't you print this model with a 3mm or even 5mm brim? It is easy to configure in slic3r.

Never used so far. Have to try it out. Does it damage model base as raft does?

Hi 3Dwithus,
a Brim leaves a thin burr around the periphery of the base, where the brim cracks off after the print is removed from the heat bed.

this can e sanded off or removed easily using a deburring tool. like this

No, the brim is printed outside the model. It comes out easily by hand. You can use an x-acto knife to cut small pieces that don't detach.
If you're using slic3r, define a brim of 3m and look at the preview. Brim is a crucial feature when printing parts with small bases.
