Itty Bitty Fitty Fitty Double Extruder Block (50% 1.75 )/(50% 3mm) (50/50)

thingiverse

The Itty Bitty Fitty Fitty (50/50) is a powerful double extruder based on Clough42's Itty Bitty Double FLEX V2 Extruder, modified to handle both 1.75mm and 2.85mm (3mm) filament with ease. IMPORTANT: This part replaces the "Double Flex Block" on the original Double FLEX V2 Extruder. You will need to download all the other parts from Clough42's page and gather all the hardware mentioned on it. Additionally, you must follow his original instructions carefully. https://www.thingiverse.com/thing:1234779 UPDATE: I recently discovered that my initial upload contained a flaw where both sides were printing with the same filament size. To correct this issue, I uploaded a new fixed version and removed the flawed one. I apologize to anyone who tried to print it and encountered problems. UPDATE 2: Through experimentation, I learned that Slic3r does not support assigning different filament sizes to different extruders. This limitation means that only one extruder can be used at a time. However, other software may offer more flexibility. Perhaps someone with coding expertise could create a custom version with the necessary settings - it's definitely an idea worth exploring.
