First thx to LogjiLink for the original design, i adapted the side spool holder for the Vision Case, otherwise it rests on the protrusion of the back.
The bracket fits but also on the orinal housing of the P1S and X1 Carbon

My print settings: 4 shells, 0,2 Layer, 25% infill (you can safely take less)
The author remixed this model.
