This enhanced version of a robust hook for the IKEA Skadis system is capable of comfortably supporting up to 15kg. While it hasn't been tested beyond this limit, it seems sturdy enough to potentially handle up to 25kg. For those intending to utilize the hook for particularly heavy loads, it's advisable to conduct prior testing and opt for durable materials like PETG. For general use, PLA should suffice. Personally, I recommend not exceeding a 15kg limit due to constraints in size and quantity of hooks. Increasing the number of perimeters beyond this point is unlikely to significantly enhance strength.
I am constantly developing more IKEA Skadis attachments. Check out my IKEA Skadis Collection here.
