Wanhao i3 Plus/ Cocoon Create Touch X-axis ratcheting belt tensioner

thingiverse

Technically, this isn't a remix because it is an entirely new model, but the idea is based on previous versions, like the remixes of PlasticCow's original belt tensioner by JF Chabot, Amzak, AlexWYYC, and others. Main features are: 1) The belt alignment is now parallel to the upper belt and aligned with the pulley/motor. 2) In addition to 1, the force of the belt is directed through the main beam, rather than below it, which lowers the possibility of bending the tensioner if running a high belt tension. 3) And in addition to 1 and 2, The main bar has been deepened for extra strength and to allow the use of the original belt fastening screws. 4) The ratchet knob has changed sides to make it easier to adjust from the front of the printer. 5) The ratchet has been increased to 20 teeth so you can print that area with fine layers. The belt fastening grooves and knob are pretty tight (They are supposed to be), so if you have trouble getting it to fit, check or adjust your flow rate. Sorry for the terrible photos because I'm not taking the printer out of its enclosure for photographing the parts. Requires a 20 - 25mm m3 bolt and nyloc nut. As per AlexWYYC's design, you may need to rotate your extruder motor so the wires don't stick out sideways.
