40 mm rail riser, adjustable length. Uses 10-32 bolts to secure to rail and 4-40 screws to affix rail together. Leave a comment if you want a different length rail and I will try to get one uploaded ASAP. Print rails with 6 walls and 8 top and bottom layers for optimal strength. The risers can be printed at 20% with standard wall settings just fine. Tree supports are needed for optimal outcomes on the front riser
