Excellent bed scraper for removing paste from a glass bed.

Glue sticks & hair spray work well but if you don't remove the old stuff completely, it will build up over time, and create bed adhesion issues as well as bumpy prints. Harbor Freight has an excellent floor scraper for removing these mini mountains from your glass bed. The item number is 93292. They have a 30% off coupon which is only good for one more day. I saw this on Friday, and thought that I would try it since I had some difficult to remove paste which was almost impossible to remove. This scraper removed the paste pretty easily without much effort. Here's a link: https://www.harborfreight.com/14-inch-floor-scraper-93292.html

 

The blade is very sharp like a razor blade so I designed a blade cover with 123D Design. TPU was used. Here's a link for the STL file: https://www.thingiverse.com/thing:3543255/files
