Gave the top clip 0.2mm more clearance. Now 6.5mm with vs. 6mm thickness of the UM side panel.

UPDATE 4-Feb-17: Added cut-outs for regular M3 nuts in the top part. Increased the length of the overlapping parts of top/bottom to 20mm (from 10mm), increases the stability. And tested to print the top part vertically, works fine and does not affect the sturdiness very much. So I'd say it's now ready for sharing and for others to print and use!
