Big Printed Lead Screw

[pm_dude 27]

So I have decided I was gonna redo my living room and wanted to change the shelf that is under the tv.

That shelf will be made of 2 or 3 thick (1 inch maybe) wood plank of about 7 feet each and wanted to use thick lead screws like these to make the feet. I should use 6.

with screwnut:

Now the question is:

Should I print those instead? I would probably need to do 2 set of 6 screws of 15-20cm each. I'm thinking at least half a inch wide. I would change the threads to be easier to print.

Could be pretty cool in bronze, copper, brass or stanless fill for the finish.

 

Anyone think it would be too weak? The TV is on the wall.

I think it would be fine if you went with a larger diameter. Maybe 3/4s of an inch instead. Just guessing though as I have no idea how strong they would actually be.

I guess it depends on what you're going to be putting on that shelf.

What does the shelf hold?

I know that BronzeFill isn't very strong, depending on what is going to be on the shelf you might want to go for XT or something stronger maybe?

Strong in what way? Compression strength and tensile strength are two quite different things

I'm not really afraid about the compression strength. I'm more worried about how it will react if I need to pull the shelf.
