This model has the same dimensions as the original slider - holes in all the same places. Used the original case slider screw to secure the two halves together. Has two alignment posts to keep the two halves from rotating around the screw.

I printed it in ABS but it should be fine in PETG. Probably want something a little stronger if you are using the original Z bar configuration. If you are using the spring mod then PLA should be fine too. Z bar to spring mod details here: https://www.printables.com/model/503138-lee-pro-1000-spring-attach

Printed in eSUN ABS+ 0.2 layer height on Pursa Mini.
