Yes absolutely. I’m sure the hobby hasn’t paid for itself, but I never expected it to. It has been worth it because of the amount of happiness I have spread with personalized gifts and a feeling of satisfaction when I make a print to fix something around the house or make life a little easier or more convenient. The little toys and doo-dads are great and the kids love them too.
It’s already a thing and AI knows about it. And yes I get the original reference.
You could try a filament sampler pack, but this might be too little of each color. Maybe buy a few packs 25 Colors Silk Shiny PLA Filament Sample Pack
Dial in your temperature first with a temperature tower. Make sure you set the temperature changes at the correct heights in your slicer. Once you have selected the best temperature, then print a retraction tower. Make sure you set the retraction changes at the correct heights in your slicer. I have an ender 3 pro, and ended up at 200° with 2mm retraction. Remember to dial in one setting at a time. Best of luck!
I use Tinkercad for simple stuff, FreeCAD for complex parts, and Blender for anything requiring sculpting. As a 3d printing hobbyist I can’t justify the price of commercial CAD software. I prefer open source when a good option is available. FreeCAD took a little getting used to, but it’s got everything you might need to create a part or mechanism for printing. Tinkercad is great for real quick simple stuff, and for blending simple models together. Software is a tool, and you need a specific tool for each specific task. Blender is the best free 3d sculpting software I’ve found.
I’m sure it’s all just courteous white hat pen testing
