To see video of the assembly, please go to https://youtu.be/Vhx3r1Wq_C8 We are a 3D print service located in Denmark. We are very dogmatic and every chance we get, we'll print the items needed instead of buying new, both to challenge our self, but also to show the world the potential of 3d print. We lubricated the bolts before assembling the hinge. You need 7pcs of 30mm long M4 screws, 7pcs of M4 bolts and 4pcs of M4 washers. Please watch the video for a guide of how to assemble.
