Very important notice！
Version upgrade notice:All DDB right-handed orders after September 19, 2020 will be upgraded to V2.0. The left-hand DDB still maintains the old model (no upgrade plan for the time being).
Orders made before September 19, 2020 will receive the old version of DDB. Please check the relevant upgrade analysis for specific upgrade content.
The old DDB only needs to purchase the new version of the shell to complete the upgrade.
▉Analysis of the highlights of the upgrade:
1: The position of the gear and the accuracy of all screw holes are calibrated.
2: Modified the new buckle, both sides of the V2.0 version of the DDB extruder support filament in and out (that is, it has no specified directionality, and you use either side of it as a material port)
3: The filament has an independent motion cabin inside the extruder. The white filament guide is made of a mixed material with lubricating properties. Its interior is very smooth, and it can withstand your crazy parameter settings.
4: A gap is reserved on the top to correspond to the threaded screw rod of the ender3 printer.
5: Brand new mixed materials, the shell is more rigid and tough.
DDB V2.1 upgrade guide:
Replaced with gears with stronger grip, under a strong bite, it will not damage the outer wall structure of the filament like inferior gears. We are trying to find the perfect bite strength. Gears have a longer life. You can almost always use your printer until it is scrapped.

Filament Guide-POM-PTFE
Filament Guide-POM-PTFE:Low friction Self-lubricating
Friction comparison chart：
Other filament guides, after long hours of work, generate a lot of friction and the temperature rises causing them to wear out.
Trianglelab, Filament Guide, uses POM-PTFE as a raw material. Smooth surface, reduced friction and no wear after long working hours.
Ultra-high hardness HV3300
HRC 60+
Hardened steel with RNC Nano Coating
High hardness for greater resistance to wear and tear
