Leather Backpack Stiffener

Another request from my wife. She loves bags but this one was losing its shape when worn. 

After a few iterations, this one worked well. It could be printed in one piece if preferred. 

Printed in Elegoo PLA. 

Spine - 0.25mm layers, 15% infill. Skirt has to be turned off as the parts fills the bed. 

Wings - 0.3mm layers but with adaptive layering on, for better resolution near the clips. 

Orientation as shown in slicer images. 

Note - the clip fit is quite tight. Step files are included, you may have to make some adjustments. I recommend you trial the clip fits before printing the full wing model to avoid waste/print time.
