Print Bed Cleaner

I use buildtak on my CR-20 and also use Hairspray to get better adherence. Now and again this surface gets messy and its very hard to properly clean. I've found the hairspray builds up and begins to leave horrible artefacts on the prints after a while.

This will use about 50g of filament if you set to 0.2 layer height @ 20% infill. Print at a relatively hot temperature, bed levelled nice and tight. Wait for it to cool a little... It will then give you a nice surface to peel off your buildtak surface, taking with it lots of the clumps and artifacts that have been left on the bed.
