Template:1.2 Dual X Rail
|Item||Part Number||Part Description||Part Count (by X size)|
|500 mm||750 mm||1000 mm|
|2||EM-S3-20||M3 20mm cap screw||6||8||12|
|4||EM-N3TI||M3 T-slot insertion nut||6||8||12|
Put a washer on each screw, put the screws through the drilled holes (screw heads on the side with the Vs), and thread a T-slot nut on each screw (one turn, just enough that they don't fall off). Hold both pieces of MakerSlide vertically, one with the Vs facing you and the single slot to the left, the other one with the Vs facing away from you and the single slot to your right. Lift one up, locate them back-to-back, and slide the nuts on each rail into the slot of the opposite rail. Align them very carefully and tighten the screws.
It is important that the rails are aligned accurately! Spend some time now to get it right, and avoid problems later.
You should now have a square 40 mm x 40 mm profile, with Vs on all four corners.
