Enclosure for 8mm bushings bought off ebay

Print two for each bushing then sandwich them together. Should make for a good replacement for the LM8UU Linear bearings. The middle band is just right for a zip tie once you've glued these together. You can find bearings for this project on ebay, search for "Self Lubricating Composite Bearing Bushing Sleeve 8 x 10 x 12mm".
