The estimated price to build the device is around 150 euros (circa 160 USD) based on a Bill of Materials presented in the Supplementary Information † . In our case, we decided to pair the pellet distributor with an electronic balance (285 euros, 300 USD approx.). Furthermore, our initial testing highlighted that it was indispensable to use an air ionizer, as the static charge generated during the filament cooling and cutting was really significant and didn't allow proper function of the device. We used the same one we mentioned in the section regarding the pellet dispenser (2.1.4), and again the need for it in the specific setup needs to be evaluated.
