Linear Rail

I've been searching for a Reliable Linear Rail that actually works, but so far, nothing has met my expectations. The ideal solution is straightforward: simply print out the necessary files, insert two 8mm round bars, assemble the sled, and you're ready to roll. For the sled itself, I opted for three Nylon Vslot wheels and four 4mm flat head slotted screws.
