Calculating 3D Print Costs with Spoolman API and Python

[vechiato]

Hi everyone! I've developed a Python script that calculates the real cost of 3D prints by integrating with the Spoolman API. It retrieves actual filament spool costs and calculates expenses based on the filament used, even supporting multiple spools and accepting inputs in grams or meters. I thought it might be helpful for others managing filament inventories and costs. You can check it out on GitHub: Spoolman Multi-Spool Cost Calculator. Feel free to try it out, and I'd love to hear any feedback or suggestions!"
