This is a minor remix of the Cheap Yellow Display horizontal stand listed on the github page. Instead of needing heat inserts, this instead uses M3*6mm self-tapping screw.
The original file doesn't have a lot of meat around one of the heat inserts so it tends to drift making putting bolts in a little difficult.

UPDATE (2024-01-18): I have made a minor update to the design to make the width of the stand thinner (from 8mm to 6mm). This was due to my reset button having a lot of sideways pressure on it (my reset button eventually came off). Both files are listed below. Have also included the Fusion 360 files for both versions. I highly suggest you print the 6mm version to stop from damaging reset button (they're still plenty strong enough for the job).
The author remixed this model.
Holes for M3 heat inserts have been changed to use M3*6mm self-tapping screws.
