Cube3 Back-2-Basics Nozzle Housing (B2B Project)

thingiverse

This is one of the three parts belonging to the Back-2-Basics Cube3 cartridge project (B2B), an initiative aimed at upgrading stock 3D Systems Cube3 cartridges, making them significantly more reliable than their stock counterparts and offering enhanced functionality with optional accessories. The nozzle components can be printed using PLA, but I highly recommend utilizing 3DS ABS for this print. It is essential to note the orientation of the parts as each cylinder has a relief for the start/stop pip. These parts are specifically designed for use on the left extruder of the Cube3; however, users with the right extruder should rotate the parts by 180 degrees. To ensure perfect results, I always utilize a cooling tower (purge tower) along with the nozzle. For your convenience, I have included a left-side ABS .cube3 file for the main nozzle components. The tube length guide can and should be printed using PLA. The nozzle core requires reaming using a #34 drill bit [dia. .111], which provides a snug but manageable fit of the tube in the core. This tube will be trapped between the nozzle and the Bowden tube when the entire assembly is complete, necessitating periodic maintenance to keep it running smoothly - a far cry from the complex process required with stock cartridges. The tubing is an integral part of the stock cartridge; therefore, you should salvage a virgin section of tubing. The optional tube length guide can be used to trim up the tubing perfectly square. This tube measures 42mm in length. It's worth noting that the position of the flange on the nozzle (push nut) may require adjustment if it protrudes too far above the surrounding area.
