Slotted Tray with Hanging Bracket

I wanted a tray that I could put my coffee mug on and hang from my wooden slat privacy screen. The bracket will fit over a ¾ inch wide board and allow you to hang the tray. The tray can be used on its own as well. The tray is 100mm x 200mm x 15mm. 

Print the brackets on their sides and no supports are needed for either print. 

I printed with eSun PETG and have made two of them so far. Both took around 2.5 Hours to print on my Sovol SV06 Ace Plus.
