it's not a lighter

     This is a vase mode print that's prone to some deformation and cracking, but still looks good and keeps a flat bottom. Works perfect with red bag fast-curing concrete (PLA cracks and peels right off), and probably others, if you tape it up.

     Basic cement/concrete pouring things, you can vibrate it to get into the fine details, stick the lighter in before you've half filled it to actually get it in properly. 
     The lighter does still work if you don't stick it too far in, although the angle is a bit awkward to keep it held down. Mostly just for the punchline. Have fun.
