locking expansion support bars
Description
These are simple "locking" expansion bars. The bars are made to expand to support something or hold something in place. Instead of printing multiple bars at different lengths you can print a few of these as an all-in-one solution. I haven't tried printing v2 or v3 but should be fine and would use less material. V1.1 is a bit tighter than than v1. Print them at 1.6 layer height or smaller.. you might get away with printing 2.0 layer height if you print v1.1 but may not lock in place very well.
