Phone / Tablet Stand

I like this stand very much. We use it all the time, its great. So please pay attention to the author. (Remixed From).

However I had an issue that needs to be fixed so I do so.
I need it for 10" Tablets so I printed it in full size. At the end of the print I get some smooth layer shifts at the point where the printer begins to bridge the connections.
I recognized this only in this design and if I scale the design it moves with the height where the bridges begin.

Whatever it is if I put an extra brace into the design and it halved the effect. And halved means now you only see it if you look carefully.

If someone have an issue with this to please leave a comment. The printer I used is the prusa mk2.5.

PS.: There is also a problem with overhangs where the cable gaps are. This I think also just happen at full scale. I don't fixed this yet. Maybe this should be parametric design.

PSPS.: I layed the model to be print ready.

PSPSPS.: As I write this I looked at the "makes"
