Test your skill and launch marbles into a moving basketball hoop under stadium lights!

The Mini Motorized Basketball Game is a collaboration project with MakerWorld to showcase the wondeful and infinite possibilities of the new Maker's Supply kit! This model features a motorized moving basketball hoop, stadium lights, a customizable sign, and an aimable basketball launcher.

The motorized moving hoop rotates twice in one direction, before changing directions to rotate twice again. I'm especially proud of this because the motor only turns in one direction, but the output alternates directions automatically using a fairly simple gear system.

The entire model is assembled using snap connectors, so no glue is needed at all and it will be simple to disassemble if you need to reuse any of the non-printed components.

Here are the non-printed components needed (all available in the Maker's Supply kit):

• 1x 0.5x5x25 mm Helical Spring (BB004)
• 1x 2x33 mm Brass Dowel Pin (DA006)
• 1x 6003 Plastic Deep Groove Ball Bearings (EA001)
• 1x 6204 Plastic Deep Groove Ball Bearings (EA002)
• 1x M2.5 Stainless Steel Hex Nut (AB001)
• 1x M2.5 Socket Head Cap Machine Screws (SHCS) (AA005)
• 1x M2.5 Stainless Steel Flat Washer (AC001)
• 14mm Plastic Balls (ZB001)
• 1x Power Distribution Board (PDB)
• 3x Jumper Cables
• 1x On/Off Switch Board
• 1x USB Power Cable OR 1x AA Battery Case
• 2x LED Board 5v Rectangle (KB001)
• 3x Wire 20cm (IC007)
• 1x N20 Series Motor with Gearbox 150rpm (LA002)

You can see the full list and purchase them from Bambu Lab at the bottom of the page!

If you have an AMS, the hoop and the court are multi-colored (with very little wasted filament) to make the project really shine!

Everything has been tested on the X1C, A1, and A1 mini! All parts fit on the A1 mini bed.

Several pieces in the project use specific settings to ensure the model operates as smoothly as possible:

• Back Wall - Only part that needs supports, luckily the supports are easy to remove
• Hoop Disk - To counterbalance the weight of the basketball hoop and the ball bearing, the hoop disk has a modifier for 50% infill on half of the model
• Court - This part is printed upside for two reasons, to allow the multicolor to print cleanly and to put the slope on the back of the model to allow the top of the model to be smooth to allow the marbles to roll easily
• Worm Gear - The worm gear is printed with a layer height of 0.12mm (0.4mm nozzle is used) to avoid using supports

All of these specific settings are accounted for inside the provided profiles, so no need to do any of these changes yourself if you're using a Bambu Lab printer.

Build Instructions

Starting with the Court, most of the parts are connected using the printed snap connectors. The snap connectors ‘snap’ into the square/diamond looking holes.

Attach the Court Feeders to the Court and insert the small Stabilizer piece into the court before connecting the Launcher Base:

Next, attach the Court Fence and the Side Nets:

Next, the Gear System will be put together:

Slot in the two identical Aux Gears into the center of the Back Wall as well as the Connect Gear:

Slot in the N20 Series Motor with Gearbox 150rpm (LA002) with the Worm Gear attached. Place the small Output Gear loosely between the two Aux Gears:

Attach the Gear Cover using snap connectors and ensure the small Output Gear from before is in the center of the Gear Cover. Connect the Big Gear to the small Output Gear like so:

The Hoop Disk Axle goes into the final hole. Insert the M2.5 x 10 Machine Screw and M2.5 Washer into the Hoop Disk Axle:

On the other side of the Back Wall. Attach the Hoop Disk to the Hoop Disk Axle with an M2.5 Nut:

Attach the 6204 Plastic Deep Groove Ball Bearings (EA002) into the Hoop Disk:

The Backboard and the Hoop are friction fit together and attached to the Plastic Ball Bearing:

Attach this finished secdtion to the main model:

The Hood and Customizable Sign are then attached on top of the main project like so:

Next, the Launcher will be put together, starting with the other Plastic Bearing:

The Launcher to Bearing part and the Bearing Cap snap together through the bearing like so:

The Launcher Base is then attached:

The small nub on the Launcher Base and underneath the Launcher Arm allow you to securely attach the 0.5x5x25 mm Helical Spring (BB004):

The completed Launcher mechanism slots into the main base like so:

Lastly, the electronic components can be press fit into the following spots on the model:

The PDB and the Switch slot into the back of the model:

The LED Boards go under the hood with the wires fed through the holes in the hood:
