Heatbed test piece for 0,3 mm extruder 150 x 180

It is 10 x smaller, so when you upload it to your print program, check dimensions to correct print. Check the units (milimeters) too. If you will have any questions, do not wait to contact me .... I will help asap

If you use glue on your bed, may it have some bumpiness like on 2nd pic.

Correct on pic.3
