Follow instructions that come with the TwistLock. Need a 6mm and 1.5mm drill bit. The edge of the track should be lined up with the edge. Adjust points so the 1.5mm hole can be seen between the track. For the 6mm hole remove the points before drilling. Placing two drill bits or any rod through the two holes will help keep it in place.

v2 clips onto the track, making it much easier to drill in the correct place for the 1.5mm. Prints best on a resin printer, accuracy is required.
