This is a Z-axis bracket setup with Z-endstop for the TEVO Tarantula 3D Printer. You only need to print both the RED Z-Axis brackets. The 'Top Z-Axis Bracket (YELLOW).stl' is for those who want to attach the Z-rod under the Z-motor bracket (like shown in example picture).
You can use the screws and nuts delivered with the printer. Parts you need to buy extra in your local hobby shop:
1x M5 nut (for the lower hole of the endstop)
1x M5 nylon nut (for the upper hole of the endstop)
1x M5 50mm bolt (with hexagon head)
2x roll bearings
Make sure your Z-axis is straight (roll it over a straight surface). Please sand the surfaces of the oldham coupler, so they all fit perfect. Don't add grease, because it will make them 'sticky'.
IMPORTANT ASSEMBLY INSTRUCTIONS:
When assembling it, you need to screw down the coupler to the z-axis first, then after all the weight is hanging on the z-axis, you screw down the coupler to the motor pin. This way no (or very little) weight will pull down on your motor and coupler spring.
The lower part of the coupler is holding the z-axis on top of the bearing, and so almost all weight is hanging on the bracket.
