Putter, ball and finish

Hello everyone! My two boys wanted to try mini golf. Since there wasn't one nearby, I embarked on the project of creating one. After a few hours on Fusion 360, I made a putter, a ball, and a finishing point. The goal is to play and hit gently. No need to be an expert. I made a clip system for the shaft so I could print it on the Kobra3. If you have a better idea, please let me know; I can modify it if necessary. Print everything in PLA. I added a thread for the lower part. I printed the "iron" without support. At 0.16 layers. Infill 25% Gyroid. For the shaft, I printed it vertically with a border for the support as well as for the inside of the square (the part that fits together). At 0.16 layers. 5 Shells 25% Gyroid filling For the ball I also recommend a support. At layer 0.16 For the final hole, no support is needed, 10% Gyroid filling, At Layer 0.2 on the Kobra 3. I made it in one color, but it's entirely possible to make it in multiple colors and add a name to the outside of the iron, so your child will be proud of their goal! I can do it for you if you can't manage it, don't hesitate to contact me directly. For the threading, your machine must be very well adjusted, otherwise you may have difficulty screwing it in. Otherwise, it's a 9mm diameter thread. If you have a screw to work it in once before inserting the handle, that might help. It's entirely possible to add obstacles to make your games more intense and fun, using everyday objects like empty reels or cardboard boxes, or children's toys lying around. Let your imagination run wild and have fun with the family! Remember, this is designed to be hit gently, and don't try to hurt anyone. french : Bonjour à tous ! mes deux garçons ont voulu essayer de le mini golf, n'ayant pas de mini golf à proximité je me suis lancé dans le projet de le créer, et voilà après quelques heures sur Fusion 360 , j'ai fait un putter, une balle et un point final.
