Hockey passing target

Ok alot here. sorry I don't know how to spell.
First off the holder you need to have supports not only touching build plate but everywhere.
Next the target it optional don't have to use that.
There are 2 rods 100mm and 50mm you can have it as long as you want with the sprocket connecter so you can have it 50 feet long if you wanted
Also to hold the item down put hockey pucks on the side.
If you want me to fix something or any suggestions please comment it.
