Wanhao Duplicator I3 Bowden Extruder for E3D V6 ReFresh

thingiverse

I drew inspiration from the latest design for this creation, calling it a refresh rather than a remix since I started from scratch. The addition of a second hole for the fan ensures its secure hold in place. Cable chain holes provide easy installation. Thicker end-stop brackets offer increased durability. The print cooler tube has been modified to compress air more effectively. Corrected X belt spacing allows use with any tensioner suitable for V2.1 printers. A bracket for mounting the BL Touch is included, complete with a slot in the back for routing wires and displaying the logo outward. The design that sparked this creation can be found here: http://www.thingiverse.com/thing:1777358 Print Settings: Printer: Modified Wanhao I3, Ramp 1.4, E3dV6 Titian extruder Rafts: No Supports: Doesn't Matter Resolution: .25 is fine Infill: 18-25% Notes: PETG was used for its toughness. Printing without supports was achievable. Bridging settings include an Unsupported area threshold of 5.0, extra inflation distance of 2.0, bridging extrusion multiplier of 120%, and a bridging speed multiplier of 170%. I recommend using 3 outer shells and 3-4 top and bottom layers, along with your preferred infill pattern. The small cylinder on the side helps maintain fan offset during rapid printing. Distortion issues arose before its addition. Post-Printing: The E3D V6 model was used as a reference, leaving room for sanding to achieve a perfect fit. The rings holding it in place are intentionally loose to allow for adjustments. A few minutes of sanding should be sufficient if needed. The 3mm clamping block holes provide a good fit but may require a small flat-blade screwdriver to prevent spinning during tightening. This was a trade-off between a tight, potentially permanent fit and a looser fit allowing for removal, which could result in stripped threads. I recommend adding a filament filter if one is not already in use. Olive oil on a sponge has been used as a lubricant with good results.
