thingiverse

This is a cooling duct for keeping the main board of an Ultimaker 2 at a safe temperature.\r\n\r\nDid you purchase a door and an Ultitop to enclose your printer, only to have all long prints fail with inexplicable under-extrusion? I did. It seemed clear that the stepper motor drivers were overheating and thermally throttling, resulting in lost torque.
