TV bracket for on a speaker stand (tripod)

I have made a mount that fits on the VESA mount on the back of a TV, these 4 M4 screws have a fixed position so the bracket should fit on the most TV’s out there.
With this mount you can easily mount a TV on a speaker stand / tripod (35mm) for temporary placing a TV.

I am using this for using a TV in the garden but you can also use this indoors in your house, or for business exhibitions and demo movies.

The TV I have mounted is 32”but I guess you can also mount a 43”.

I have made the bracket from scratch in Tinkercat and have you can put a M8 nut inside the top and use a M8 bolt to lock the Tv on the speaker stand.
For making the locking more easy I have add a knob that I found on Thingiverse from user Glompie: https://www.thingiverse.com/thing:2451628

On the picture you can see a tie-wrap this won't be needed but when I glued the nut in place my bolt was glued on the nut while removing this the print had a small crack and I pleaced the tie-wrap just to be sure.

Printing will be done upside down. No supports are needed and wanted to make inserting the M8 nut possible.
