Excited to share my latest 3D model – a J-shaped wall hook that's as simple as it is strong. This design is all about practicality and strength, and I've included two versions in the project to suit different needs.
 

Adhesive Version (Plate 1):
This one's for those who prefer not to drill holes in their walls. It sticks with strong double-sided adhesive tape (the kind you find on Amazon). But remember, the weight it can handle depends on the adhesive. 
 

Screw Mount Version (Plate 2):
Need something sturdier? This version has two 5mm holes for screw mounting, offering more strength and a higher load capacity. I've tested it with around 8 kg, and it's held up well, but I'm planning more tests to see just how much it can really handle.

I've designed these hooks with kids' rooms in mind, making them in multiple colors to brighten up the space. They're not just practical; they look great too.
 

Regarding printing, I've included a brim to counter the top lifting issue I've noticed. Feel free to ditch it if it's not needed for your setup. I use a textured plate for printing, though a smooth one might yield different results.
 

I can't wait to hear your feedback and see the results of your prints. Your experiences, tips, or any modifications you make could help improve this design further.
