Summary I've created this to use the Celestron as a tripod to film with the One Plus 3 phone. https://cad.onshape.com/documents/f3302bedd0727bb9d0cd8465/w/c85c80087b861ed73c6d6a59/e/2bd89d1d426457e87949fd79 I just uploaded a new v2 STL with the fixed for what I consider failed on the first one. I use mine with phone case. On the original SLT, I didn't use the original screw, I use a normal screw. What I'd change on the original: Increase the height of the support by 2 or 3 mm so I can use the original screw Use a wider support for the phone with reinforcements. Today is 1mm, I'd go wiith 2.
