Tennis Trainer

My son showed me this YT Shorts video that had a similar injection molded product. The channel was trying to sell it for $40. I checked Amazon and saw it for $10. So, naturally, I figured I could challenge myself to make it cheaper so I made one that was easy to fill and could be printed quickly in case one wasn't enough. There is a divot for the tennis ball for when you're carrying it and there is a hole for the rubberized string that comes with the tennis balls for practice. This is not a water tight model, so I would just fill it with cheap sand. The injection mold project was very curvy, which is not great for prints, but I added some curves where I thought it'd do well. Glad I did this model, I learned how much of a pain support painting inside a model is in Bambu. Does anyone know how to get the scroll down layer line thing in the Prepare mode? It'd be really useful to paint without having to cut the model.Enjoy!
