ISOFIX SYSTEM for umbrella, documents, bags, etc

MembershipIf you like to sell my model, please subscribe for 10$/ Month

I’ve designed and created universal holders that fit perfectly into the ISOFIX (TOP TETHER) mounts in your car’s trunk.
Use them to hang car care bottles, brochures, umbrellas, or to secure your grocery bags—keeping everything neatly in place and preventing it from sliding around while you drive.

 

Boost MeBoosting is FREE but it helps us makers run this hobby. i put a lot of effort into this and would really appreciate it if you supported my work and future updates

How-To
 

• Use the BASE firstly and slide it onto the Top Tether/ISOFIX

Print the Hook/ Holder you like and slide it in to the Base

If you like to attach rifles, or other heavy things i reccomend using the right and left 2020T profile adapter and buy the needed length for your trunk.
Then use regular V-slot nuts for 2020T profiles to hang wathever you like the most.

 

Happy Printing ;)
