Overall works great and I love the screw mechanism. My only suggestion would be to increase the infill to 25%, at least for the brackets. They felt a bit week at the radius. Also maybe consider adding some chamfered holes for mounting. Other than that its great! Thanks for sharing it.

Exactly what I needed. I used this as a base for a unicorn I printed and painted.

Came out great. I printed this in grey and painted it up.
