Migbot I3 Y-axis belt tensioner

A Belt Tensioner Bracket for Your Migbot I3, Perfect for Adjusting. You will need to create a small opening in the part that houses the adjuster screw using a drill bit. This tiny detail should be an M3x30, but if you are feeling bold and adventurous, consider countersinking the hole slightly and swapping it out for a stronger M3x20 screw along with a secure nut to prevent any unwanted slipping. Timing Belt Pruning Required: Reduce it by 30mm. For installation, we recommend trimming back the timing belt a generous amount of space is needed. Print at a decent thickness such as .3mm. Although ABS may also work if that's your preference. Printing Recommendations: Base Useable Template. Mount to frame on opposite side temporarily and create the adjuster screw hole before you put everything together.
