Prusa MMU1.0 PTFE Tube Adapter - 4-7.4mm

thingiverse

I'M FEEDING MY STEPPER MOTORS FROM THE SIDE OF MY ENCLOSURE WITH SOME 6MM PTFE TUBES.\r\nSO I DESIGNED AN ADAPTER TO ATTACH THE PTFE TUBES TO THE STEPPER MOTOR HOLDERS.\r\n\r\nI HAD TO LEARN IT THE HARD WAY:\r\nIF YOU'RE USING THE STANDARD 4MM PTFE TUBES, THE INNER RESISTANCE GETS TOO HIGH AND YOUR PRINTER QUALITY GETS WORSE.\r\nSO I ORDERED 6MM TUBES WITH 4MM INNER DIAMETER. THAT WAY EVEN WITH A FEW STEP CURVES THE FILAMENT HAS ENOUGH PLAY.\r\n\r\nTO ATTACH THE TUBES EVEN BETTER, I ADDED A SMALL SILICONE TUBE BETWEEN.\r\nTHIS RESULTED IN THE FINAL 7.4MM VERSION.\r\nYOU MAY COULD ACHIEVE THIS BY ADDING SOME TAPE BETWEEN\r\n\r\nPRINTED WITH:\r\n4 PERIMETERS\r\n5% INFILL
