I just purchased a used Cube 3 printer. It's my first 3D Printer. It came with a lot of cartridges (some never used), as well as 4 tubes of the "print glue"

It did not come with the starter kit, which would have included the sandpaper, the plastic "manual gap setting" tool, the scraper, and the nozzle wipers.

I figure I can use painter's supplies from Lowes for the scraper (metal) and nozzle wiper (plastic) easily enough.

But what grit is best for the sandpaper?

And what thickness is the plastic for the gapping tool?

And not that I'm going to run out any time soon, but I've been reading that simple "Glue Sticks" are good to prep the platen surface?

Thanks in advance from a newbie.
