Prusa I3 Hephestos - Adaptador filamento flexible

thingiverse

After many tests I have managed to optimize this adapter design to print without problems with flexible filament on our Prusa i3 Hephestos. The piece is located between the motor and the barrel entrance. It is necessary to add a piece of PTFE tube, cutting it in such a way that it does not protrude from the top of the piece and also does not pass through the lower larger hole where the hotend barrel will be inserted. The sequence for correct installation would be: Remove motor and remove hotend. Place the piece in its approximate position. Place the motor aligning the piece with it. Insert the hotend so that the barrel enters the hole adjusting perfectly the piece so that it is completely aligned. I recommend printing in ABS, layer height 0.1 mm/s speed 20 mm/s, no supports.
