Tetrix Chain Tensioner

thingiverse

This chain tensioner is engineered to compensate for slack in the tetrix sprocket systems. It's not intended to support any weight, but rather absorb tension and remain idle when at rest. You'll require two of these units positioned on either side of a channel, each with one Bronze bushing securely in place and connected by an axle that spans the distance between them. To ensure stability, lift up on the tensioner and tighten its screws; they should hold fast once secured. To prevent damage to the plastic components, recommend installing a washer under the screw's head. Printing specifications: Rafts: Disabled Supports: None required Resolution: Set at 200 microns for precise results Infill density: Target a solid infill rate of 90-100% for optimal part thickness Notes: This design features a very thin profile, requiring almost complete infill to prevent sagging. Important consideration: The tightness of the bronze bushing in its mounting hole may vary depending on your printer's calibration. If it doesn't fit as intended, try enlarging the hole using a 5/16 drill bit and drilling manually, or if that method doesn't work for you, an 8mm drill bit would be the next best option. Repeat this process until the bushing can freely pass through.
