Update 2019-08-21 :
Version 4 guide: use collet and clip to secure bowden to guide, use genuine E3D 4mm bowden collet for 1.75mm filament, the clones are too big and will not fit
Update 2019-02-02 :
Version 3 guides : enlarged fitting hole radius by 0.1mm for easier mounting and to prevent cracking, added tensioner to guides to allow for spring tension adjustment, use 15mm or the stock 20mm spring, 2 tensioner length provided. If you prefer the fixed tension, continue using version 2
Update 2019-01-27 :
Version 2 base : minor tweak, use 8mm m3 lock bolt, added base with tube support
Update 2018-11-04 :
Version 2 guides : improvements to guides: minimize gap to optimize for flexible materials, use M4 nut to secure bearing
Update 2018-09-14 :
Version 1 : improvements on the base (retraction stabilizer and reinforcement) and guides (more room for gear, plunger, rounded edges)
This design is inspired by SeeMeCMC EZR Struder, I had been using it for over a year on my CR-10 until it finally broke on me. This is designed…

dTitan Geared Extruder is based on E3D Titan extruder spare parts: the gear and hobb
External look and idea was taken from my remix Drakon reinforced extruder (https://www.thingiverse.com/thing:2575076) of Drakon Geared Extruder (https://www.thingiverse.com/thing:2172854)
The main difference against https://www.thingiverse.com/thing:2575076 is using manufactured gears from E3D Titan kits.  Interior of the extruder was significantly changed and adapted to use those gears
The gear ratio is same as on E3D Titan. It can be used In both setups Direct Drive and Bowden. You can redesign the spacer part dtitan-p3d.stl to fit any other mounts
