GEEETech i3B: Extruder End

thingiverse

After a month of using my GEEETech i3B with its complete cable management system, ventilation fan, and various small LEDs, I've made some minor updates to (hopefully) solidify the solution: 1. Changed the X-chain attachment so that it minimizes the curve inside the vent's grommet, allowing it to pass perfectly over the frame without losing any useful height. 2. Redesigned the air outlet channel from the extruder to incline the LEDs at a 45-degree angle, which now illuminates the printing area perfectly. 3. Added support for the auto-bed sensor - actually, I added a compatible sensor since I don't have the PiBot yet, but the resolution isn't enough... by September, I'll switch to the PiBot, but in the meantime, the support and cables are already there. 4. Added a rear LED to illuminate the filament change zone, so that at least this annoying operation is done with sufficient light, which makes it slightly easier. 5. Added a three-position deviator so I can control the access of LEDs - both for the filament change area and those illuminating the printing area. 6. Added M1x10 threads for easy assembly without any doubts about correct positioning, using glue (Attack in my case). All STL files were generated by me from the 3D model made with AutoCAD (faceres=10) and treated with 3D Model Repair to make them perfect... UPDATE: The heat of this period has led me to restore the previous air conveyor design from the auxiliary fan, commanded via D9... it's the design with the vent at a 45-degree angle, which in its first incarnation disturbed the filament change slightly, a problem that this new version doesn't have, and forced me not to turn on that fan before layer 4 because otherwise it would cool down too much. But given these temperatures, I'd rather have too much cooling that can be turned off!
