Spark endless hours of creative play with these Kid's Fort Ball Connectors! Designed for 10mm wooden dowels, this system allows your little architects to build amazing dens, castles, tunnels, and whatever their imagination conjures up.

Why THIS Fort Connector Is Awesome:

  • 🌟 Elegant & Customizable: Designed for standard 10mm wooden dowels (poles). This offers a more aesthetic and natural feel than PVC pipes, and you can easily paint or decorate the poles!
  • 💰 Super Filament Saver: Say goodbye to filament-hungry connectors! Each ball uses less than 10g of filament, a massive saving compared to many designs that can exceed 100g per piece. More forts, less plastic!
  • ⏱️ Lightning-Fast Printing: Get building sooner! The included print profile is optimized for speed, especially with a 0.6mm nozzle. Print a full plate of 25 connectors in under 6 hours and 30 minutes! (A 0.4mm nozzle profile is also provided for flexibility).
  • 🎨 Fun & Practical Design: While optimized for print speed (because let's be honest, forts see a lot of action and parts might get "battle-damaged" by enthusiastic kids!), these connectors are plenty sturdy for epic constructions. Print them in various vibrant colors to make an extra special gift! Quick to print means easy to replace!

Get Started Building Your Fort Empire:

  • Recommended Starter Kit:
    • Print at least a full plate of connectors (e.g., 25 balls on a Bambu Lab A1 Mini).
    • Gather around 30 wooden dowels.
  • Wooden Pole Pro-Tip:
    • Look for 10mm (approx. 3/8 inch) diameter wooden dowels. These are commonly available at hardware or craft stores.
    • I purchased 2-meter long dowels and cut each into 6 pieces, resulting in poles approximately 33cm (13 inches) long. Feel free to customize lengths for different structures!

Print Settings Summary:

  • Nozzle: 0.6mm (for speed optimized profile) or 0.4mm (alternate profile available).
  • Filament Usage: <10g per ball.
  • Estimated Print Time (0.6mm nozzle): ~6h 30min for 25 balls.
  • Material Recommendation: PETG is a good choice for its durability and slight flex, though PLA works fine too, especially given the low cost and speed of printing replacements.

The model is great and also saves filament. After some test prints and trying out the fit, I decided on a scaling of 96%. The rods don't slip through and hold very well.

The print was ok, the file is really cool. I bought extra 10 mm round rods, but the whole construct is very wobbly and unstable. Therefore, it will not be used here anymore, unfortunately.

I tried printing it twice with a radius of 5.7 mm, but both attempts failed. I was making it for my child. Do you have any suggestions?

Hey, you mean 5.7mm diameter rods? This seems small. How does it fail?

Replying to @julienma :
The diameter is 11.4 mm. It doesn’t stick to the build plate, so the print can’t continue after about halfway. But when I added supports, it worked.

Replying to @idoksanbir :
Oh, you mean the hotend is colliding with the ball mid-print? Make sure you clean your plate properly and add a bit of glue to ensure great adhesion. I suppose supports do the job. But it's gonna be a pain to remove them if you print a big batch of balls.

like you can put the together and twist them so they stay together and you can have longer and shorter ones.

They're meant to be used with wooden poles, 10mm diameter. I purchased 1m long wooden dowels which I cut to a length of about 30-35 cm.

I also got some adhesion problems. I ended up placing only 8 pieces per plate, as far from each other as possible and added a 1cm brim. Than it printed ok. Using 10mm poles i noticed that some holes are much tighter than others. The hole size isn't very precise. Anyway, i think we will have fun with them! Thanks!

They're not the strongest types, they're meant to be fast and economic. When they break, they can be easily replaced. In my case this strikes a good compromise. Anyway, maybe PETG could help if you didn't already try?
