This is my Ultimate Carriage for Anet E10. Inspired by several other models here (by MrCrankyface, Boounscoils, lepetitstudio, others), but totally designed from a scratch.
Using Derlin double-bearing V-Wheels, SUNON 40x10mm quiet fan, two generic 50x15mm turbo fans. Also implemets x-belt paralyzer in one model.
Assembling process is pretty clear on the photos, but if you have questions, feel free to comment.
M5x30 - 3 - for Derlin V-Wheels
M5 lock nut - 3 - for Derlin V-Wheels
M4х30 - 2 - for bottom V-Wheel part
M4 square nut 7х7x3mm - 2 - for bottom V-Wheel part
M3х10 - 2 - hold fan duct from behind
M3х10 - 2 - hold fan shroud и fan duct in front
M3х14 - 4 - hold fan
M3х18 - 2 - hold turbo fans
M3х20 - 4 - hold paralyzer
M2х10 - 2 - hold fan shroud and bridge
M2x12 - 2 - hold X-axis end stop switch with spacer
Used different types of support, depending on the part, infill 20% with 0,8mm line width. Nozzle 0,4mm at 207C, filament PLA 1,75mm, hotbed 50C.
Don't forget to insulate the hot end (heater block), otherwise it will start melting slowly!
For this you can use regular PTFE tape (Teflon tape) from your local hardware store.
The bridge was first screwed to the fan shroud, then glued to the fan duct, using regular super glue gel (Cyanacrylate). Cyanacrylate residue is also white, so is invisible on the model.
You may skip using the bridge to support the fan shroud from beneath if you have trouble finding M2 screws or just find it excessive. Fan shroud sits normally with just two upper M3 screws in place.
You may need to adjust hole sizes, depending on the plastic and printer you're using.
Mine has about 0,2mm horizontal shrinkage, so I designed all holes 0,2mm larger than they suppose to be, so the screws sit tight in the holes.
You also need to print out and install a spacer for X-axis end stop switch, which is in file E10_UltimateCarriage_07_Spacer.stl
Also you will need 2 M2x12 screws to hold the end stop switch with the spacer.
