Vintage Pachinko Machine

Pachinko has always been a childhood favorite, using wooden boards for the base and nails for pegs. Last time, I saw Renaar's Pachinko machine https://makerworld.com/zh/models/1312291-vintage-pachinko-ode-to-retro-elegance#profileId-1346761, and I wanted to make my own version. Also, since I bought an H2C, I wanted to make a larger Pachinko machine. I also learned a lot from Renaar's design for the entire Pachinko machine

Materials:

(In China)

1.  Brass dowel pins 2x13mm https://detail.tmall.com/item.htm?id=785565772431&mi_id=0000q7jfzPLjLoQ4v_Ao8jXCuMgEt6sfzicGSJtupHkqxIQ&spm=tbpc.boughtlist.suborder_itemtitle.1.263f2e8dwli0yV

1. The entire design avoids screws, using mortise and tenon joints throughout. For added sturdiness, glue can be used
2. The feet at the top and bottom of the Pachinko machine have been optimized (different from the photos) to significantly reduce PLA filament usage
3. A box for holding marbles is designed at the bottom of the Pachinko machine, requiring 8 magnets (6mm diameter, 2mm thickness)
4. The entire assembly requires a rubber mallet to avoid damaging the model
5. Items to purchase are: 1) Brass dowel pins 2x13mm, 2) Springs 0.6x12x7mm, 3) 10mm stainless steel balls
6. It is best to use more perimeters (5-6 perimeters) to prevent structural breakage during installation and to avoid the brass dowel pins piercing straight through
7. The pull rod is thin in the middle, so it is printed flat as a semi-cylinder to ensure strength
8. For pull rod installation, first insert the spring, then the pull rod, and finally secure it with a small pin
9. The holes for the brass dowel pins might be too large or too small depending on the machine, so it's best to test before printing
10. The entire model requires a significant amount of printing time. Please be patient and finally enjoy the fun playtime
