Harbor Freight Mini Mill Column Top Cover, Solid, Hole, or Slot.

Decided to make a cover for my Mini Mill column with the Air Spring upgrade. I was originally going to disassemble the air ram to install in a hole but got lazy and just made a slot. Included the hole design just in case anybody wants it.. Also included a solid version in case you dont have the air spring upgrade. Fits snug and wont fall out, I was able to push it in with my fingers. Thought about putting a hole and a slot in it for the chuck key and a wrench but didn't, you may want to open up in tinkercad and do that.
