I printed everything in ABS and .20 layer height, tube had to be printed slow, this differs from the original because my filament spool was on the left of the printer, so I made a bracket to keep using the roller.
Original Description
This is a filament guide with a roller to directly feed from a filament dryer from bottom.
I printed it with 0.6mm nozzle and with 0.4mm layer height, but add variable layer height for the roller. 0.2mm layer height should be fine.
The author remixed this model.
Added a 90 degrees bracket
