Smaller and improved version of my other acoustic panel folding hook for panels with 13 mm wide and 10 mm deep spaces between the bars.

Print in place positioned at front face, tested with 0.2 mm layer height, 0.4 mm nozzle in PLA+ and 25% infill. The joint should be loosened with force and then moved until it no longer sticks. If this does not work, reduction of layer height, flow rate adjust, reduction of print speed can improve the situation.
