Saved me hours of continued tweaking by showing me my bed wasn't as clean as I thought it was. After ALL my prints started randomly failing catastrophically, my first attempt, I cleaned the nozzle and tried again. The second attempt lasted longer BUT I noticed that the spot where the "hole" was in test 1 had a different sheen than the rest of it... Took the plate to the sink and have it a nice long wash resulting in the 3rd test completing stunningly. Absolute life saver!

Kiddos love them! Customized the plates so they could keep track of ho many sensu beans they've earned
