Conduit Rail Shelf - Guide

Using standard electrical conduit off cuts I made brackets to hold 2 lengths and it is extremely sturdy. This can be used as a filament spool holder option or for using the rails as guides for a moving plate. My use is for a router plate rail guide to level a tree ring made into a trivet, I made the legs so that they can be clamped to a table as an option and they are extremely sturdy. However, my round 1 router plate holder worked enough to get through my current project but not well enough to consider complete for posting (next round will have bearings). There is also a test piece to use for size checking without wasting too much filament.
