Robo 3D R1 Full Carriage / extruder assembly for E3D V6 and Hex(Screwless)

thingiverse

Fixed some things i didnt like about the original carriage / extruder expecially mounting a E3d V6 . The screws that deform the E3d to lock it in is a bad idea imo .It deforms the hotend metal (bad),eventually destroys the hotend if reinstalling multiple times, the hot end always ends up crooked etc . So i created a new Carriage and extruder so the hotend slides into the carriage and tightening the extruder to lock it in. You do lose a few mm in z travel since the hotend sits lower and carriage is thicker but thats trivial. Also upgraded on the carriage is a new x belt mount design .This allows some tension adjustment by way of adjustable 3mm screw tnut slot . The carriage accommodates a Tslot fan mount on the back . 40mm screwless Fan mount also included in files designed specifically for this carriage. ADDED: STL for Carriage specifically for Hexagon Hot end . Uses same extruder STL .Difference between other carriage is this one has a mounting depth 1mm shorter for the hex shorter lenght heatsink groove. The extruder is specifically designed for this new carriage . Hotend hole specs made for the E3D V6 . Added a ziptie tab to hold wires. Fitment: The fan tslot needed a litle post process sanding to slide into the carriage easily.You can modify the solidworks file and make the tslot slightly small to avoid and post processij. The LM8UU bearing fit nicely in the carriage .Just put it in a vice and it pops in witth minimal force. REVISIONS: 3/15/16 Fixed the fan tslot issue . New file _tslotADJ REVISIONS 4/3/16 Added files for WadesHeX extruder and HexCarriage Added 4/27/16 : Herringbone gears i use with this setup REVISION2 10/7/2017 E3D Carriage belt tensioner and Tnut upgrade (HARDWARE NEEDED 1x 3mmx6mmL screw ,washer and 1x 3mm Nut ) If you like the part , please donate .Thanks :) Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: No Supports: Yes Resolution: .2mm Infill: 100% Notes: The carriage is best with 100% infill. It can be flipped upside on the bed if you prefer to print it that way . -Sliced in S3D Post-Printing it was brought to my attention that the belt tensioner can be a little weak. I havent had any issues with the 2 i printed but you may want to use washers at each end of the tensioner screw to cover more surface area and not compress and break the plastic. Another thing that will work is just printing a tube that can go over the screw between the plastic to give it more structure and allow more tightening. I will be modifying the file with a better tensioner design when i get a chance . Revision2 10/7/2017 New belt tensioner design (Slide and lock Tnut)
