About this 3D model

***** As of 2026 all my files have been moved to Printables - find me there - https://www.printables.com/@CwthDynamics_4181414 ***** Flashback to MakerBot 2X and Carl Raffle's upgrades. This is an extruder upgrade to match with Carl's Alu-Dual Block. Between Carl's block and rmcniff's extruder I was able to print PLA on my 2X for the first time ever. Instructions Print in ABS or similar - PLA will not work. You will need: From original extruders: bearing & shoulder bolt. M4 x 10-12mm flathead or #8 x 3/8 - 1/2" (For bearing) M3 x 5-8mm flathead for attaching base to motor Spring - I used rmcniff's suggestion: http://www.mcmaster.com/#1986k5/=qtpbwl Rather than repeat rmcniff's excellent directions: http://www.thingiverse.com/thing:222667/#instructions
