Scotch Blue Tape this is a hint

I use scotch blue painters tape
You don’t need the scraper anymore, I read this clue and it’s a great thing to print.
It works perfect with PLA with ABS I don’t know yet.

quick question on this. Does the heatbed need to be turned off? Or it doesn’t matter?

You can use a heated bed if you want. I always have with blue tape… TBH though I’ve found the bed stickers are almost always better. I found this guide that does a good job of explaining the best practices of using blue tape if you are wanting to try that over the stickers.
