About this 3D model
If you're planning to connect a whole lotta solid polypanels, this tool may save your fingers from exhaustion! The Polypanel Connector Tool prints in one piece without supports, ready to use off of the bed. I was printing at 100% infill with Polyalchemy filament and got great results. Printing with Fillamentum Extrafill PLA afterwards led to a more stiff tool, so I suggest possibly going down to something like 3-4 shells and 30% infill for a more flexible tool. Let me know if you have any helpful results!
