Satchel Chest Strap Clamp (prevents slipping)

The chest strap of the school bag (Step by Step brand) tends to slip upwards.

To prevent this, I designed this little helper.

Instructions:

• Push the chest strap further down to create space for the part at the top.
• Slide the part onto the guide so that the wide end is at the top.
• Once the part is fully on the guide, push the part upwards into the small pocket above the guide.
• Done. The part now blocks the chest strap and prevents the strap from slipping.

The part is symmetrical and can be used for both left and right sides. Simply print 2x.
