Step 1
First attach the printed tensioner to the motor like shown above
Step 2
Then attach the lower bracket of the motor mount to the frame
Step 3
Insert the M4 nut in the upper half of the motor mount and attach it on top of the lower mount and to the frame with M4 T-nuts. Don’t forget to tighten the two halves to the frame by screwing down the 40mm M4 into the printed M4 holder you inserted when assembling the frame.
Step 4
Attach the lowest part of the tensioner and motor, screw down the M4 in which the tensioner slides until it is snug, but the tensioner can still slide smoothly.
Step 5
Finally attach the small side panel piece and attach the front brace/integrated hinge and tensioner knob. The hinge and door assembly can also be installed now but for ease of working it is best to leave it off for now.
Step 6
Repeat for the other side
