I was able to print it on both PLA and PETG with no support material or brim and 100% infill. 📷 Image redacted — claim this model to add your own media I'm using the above model on a regular basis for a few days. It is a smaller version that I used for testing and it ended up working just fine as an armband chain. 📷 Image redacted — claim this model to add your own media The smaller model is ~20 cm and the bigger model ~55 cm long. 📷 Image redacted — claim this model to add your own media
