Model Train Cradle

I enjoy model railroading, and wanted to build a cradle to hold models that I am working on. This 3d model was designed to make that work easier.
Here are some of the features included:
Rounded storage cups for screws.
Under the storage cups are slots to hold strong circular ndy magnets 32mm dia. 3mm thick.
Back side has storage for precision screwdrivers.
Back side has key slots for drywall screws to hang on the wall when not in use.
Pillars added to the front edge for future addition of flexible helping hands. Hole is 1/4 in and ACME threaded.
Plastic is slippery, will add single sided foam tape for protection and grip.
Built to fit Ender 3 build plate. For larger O scale trains, two cradles may be needed.
I hope this helps other model railroaders and look forward to seeing remixes.
