This is a 10 inch rackmount for a TL-SG108 /TL-SG108E / TL-SG108S

This prints diagonally on the bed and fits a standard Ender 3 / i3 bed with it's print size being 208x208, print face down as provided, if you have a larger bed then rotate by 45 degress.

I've used two joined together cable ties to secure (using holes provided). It has a beveled front as I have wrapped mine in vinyl wrap, but looks fine unwrapped too (photo is a work in progress project)
