Only thing you need is IKEA TISKEN (← click to open). Print both parts, insert first part onto the IKEA holder and slide the second part in. According to IKEA, each hook can hold up to 3 kilograms! - Your phones should be completely safe :)
Printing details
*In my case, I was able to print this well without supports using bridging only
I had very nice fit when I connected both parts, however I own only Ender 3 pro. This means that I need you to give me feedback about how well it prints on other printers.
If you have any feedback to make this better or some request, feel free to send me a message - I will try to help. Thank you for downloading my models!
