TPU Extruder adapter
thingiverse
This is an adapter for printing with TPU flexible filament in the dual gear extruder for the Ender. Printing with TPU without it can give problems when filament gets out of the gears. With this adapter the spaces are covered and the filament can't get out of it's place. Can be printed top side down to avoid the need for any supports. Printed in PLA with 0.4mm nozzle and 0.16mm layer height and 10% fan speed for increased resistance. Once printed, remove filament from extruder and put it pressing down gently. It fits tight so it may be a bit difficult but it should get in position with no problems.
