It prints wel. The comb part warped a bit, but its still functional. As with PLA prints, spray it with 50% ethanol /water solution to unstick the print. I may adjust the model to make it more comfortable.You need to have some hair for the comb part to work. The design of the comb makes it stay in your hair after you take off your surgical mask so it wont fall on the ground by mistake. Removing the mask is not as smooth as it can be and can cause the comb part to pull on the hair if both sides arent done at the same time.
