Titan Aero Carriage for D-bot Remix of the AC-Bot Carriage 2.0 by Sparreau ####Modified to Allow for 26mm or Longer Stepper Motors. Big thanks to Sparreau for the original design and Fusion360 files. https://www.thingiverse.com/thing:2822853 #####Features of Original: 1. E3D Titan Aero mount 2. 3 wheel X carriage with adjustable tensioner 3. Adjustable belt tensioners 4. Mount for C shaped cooling shroud using 50mm blower 5. BLTouch probe mount #####Modified the Original Files with Following: 1. STLs rotated for print orientation 2. Added sacrificial bridge layers to unsupported bolt through holes, no supports needed now, just cut out with knife or drill. 3. Modified rear plate to fit 26mm stepper motors commonly used with Aero. #####Update April 4: 1. Front plate got mirrored somehow, sorry about that, corrected file uploaded now. 2. Noticed nut pocket for fan shroud on 26mm stepper backplate may not be deep enough for average M4 nut, replaced with modeled M4 thread to save space. 3. Added photos of first test prints in PETG. #####Update April 4 Part 2: 1. Uploaded new back plate for 26mm steppers, should have about 27mm of space now. 2. Changed nut pocket to modeled M4 thread, shroud isn't heavy and other nut pocket would probably be enough to hold it securely anyway. 3. Added more clearance for 26mm steppers. #####Update April 5: Uploaded modified fan shroud that gives more clearance for 26mm steppers, uses less plastic, has larger opening for blower, and has more forgiving bolt hole for securing blower. #####Update April 11: Uploaded new version of rear plate and fan shroud with complete clearance for stepper motor longer than 28mm. #####Update April 18: Uploaded new version of rear plate that fits E3D Slimline 25mm stepper motor, flare made it impossible to fit front and back together, now has cutout along arm that drops down for shroud holder. #####Update April 19: After test fit assembly, realized shroud was too low on my setup making it equal in height to nozzle tip, adjusted rear plate to raise shroud by approx 2mm. #####Update April 20: Uploaded file for rear plate that raises shroud 2mm bringing it in line with clearance for BLTouch pin, printed and tested working. Noticed belt tensioners are slightly further back and pull belt slightly out of alignment with idlers on H arm ends, unsure if it's enough to cause issue, may modify idler blocks and backpack and rear plate to move them farther forward. ####Hardware Used: - M5 40mm x2, M5 35mm x1, M5 hex nut x3 for wheels - V-slot mini wheels x3 - M4 30mm x1, M4 washer x1, and M4 hex nut x1 for blower mount - M4 12mm x1, M4 8mm x1, M4 washer x2 and M4 hex nut x1 for fan shroud mount (26mm stepper) - M3 16mm x2 and M3 hex nut x1 for belt tensioner blocks - M3 20mm x4 and M3 hex nut x4 for wheel tensioners - M3 12mm x2 and M3 hex nut X2 for backpack - M3 8mm x2 and M3 hex nut x2 for BLTouch mount - M2 12mm x2 for micro switch ####BLTouch Nozzle Offset X: -41.8mm Y: +32.2mm Z: +2.3mm You should remeasure the Z height to be accurate to your setup.
