About this model

Anatomical heart with a loop that can be used as a keychain or necklace pendant. The loop has been thickened to increase its strength and reduce the risk of breaking during use. Printing I recommend printing the model with supports, configured for easy removal while minimizing marks on the surface. The model is already oriented in the position I consider most suitable for printing. This orientation helps increase the strength of the loop by aligning the layers more favorably with the forces applied during use. Avoid printing the model vertically, as pulling on the loop could cause separation between the FDM layers and lead to breakage. The 3MF file was prepared in OrcaSlicer and already includes the support settings I used.
