Armrest for IKEA JULES children's desk chair

Ikea Jules is a nice chair for kids, but they tend to sit on it in all possible positions. I've designed simple armchairs to help my daughter sit straight in front of her desk. The size was limited by my printer - Prusa MINI+. I'm including source files for Fusion 360 so you can change the size if you have a bigger printer. Please note that the design is far from being fully parametric

You will need some screws (for each side) for mounting and reinforcing the structure:

• 4 wood screws (3.5x16mm) for mounting it to the chair
• 2 long screws for reinforcing the main element - I've used M5x60, but the hole is designed to be 100mm long
• 3 short screws for reinforcing the corner - I've used M4x16
• 3 screws to reinforce the mount plate to the main part joint - I've used wood screws 3.5x60mm

I've printed it on the side using PET-G, using supports, 0.2mm layer height and 40% infill. The .3mf file includes my print setup
