    Well, I'm just surprised this printed as well as it did.

    If that were all there was to say, I wouldn't have bothered. However this did generate a small challenge in printing. Even with a first great layer, the total amount of (in this case PLA) material touching the bed is small:

    On the first attempt, after a few layers, the belly to be came loose and so, some better grip was required. In this case, I decided I would achieve this by using a flexible material for layer 1, as for me, that stuff is always a challenge to remove even after cooling, so I figured it would provide a strong base for this problem. All I needed then was to insert a filament change (M600 if you have support) into the GCODE before layer 2.

    This single layer really helped keep the lizard still for the print and confirms that PLA will print and stick well on top of a flexible material.

    I've never found rafts to be useful before; quite the opposite. I'm curious if anyone else has tried using a flexible material as a first layer for tricky prints?

    That is pretty amazing looking. Clever solution to getting it to stick too!

    wouldn't a brim work just as well?
    Also what is your bed surface?

    Thats cool, I must admit I used rafts for my two Draudi's.

    I did that. I just got tired of cleaning the mess regularly. With the PEI bed you just print, wipe, print, wipe, print, wipe. It's just too good to be true compared to other surfaces I've tried.

    Printbite is like a pei sheet but a glossy and a slightly more giving material so no elephants foot

    Ah. Clearly I didn't use that stuff then. I got mixed up with Wolfbite. Given that I'm not using the glass print bed anymore I might give this a go. I also have some BuildTak lying around that I've never tried with a heated bed.
