A phone holder designed to hold a smartphone, and this model has another advantage: it virtually eliminates empty travel. Sometimes, printing with the print head moving while heating yields better results, but if the print head does move without extruding material, stringing can occur. The solution is to avoid empty travel altogether. This phone holder not only serves its purpose but also allows for printing with the print head moving during heating without causing stringing. Even when the filament is slightly damp, the printed parts maintain decent quality and require minimal post-processing.
