Parkside PMRA 20-Li Lawnmower Wheel for A1 mini

This wheel is designed to replace the original wheel of the Parkside PMRA 20-Li lawnmower.
The design is inspired by the one shared by @Tekkna, whom I thank for the excellent starting point.

🔧 Modifications Made
To make the model printable even with the Bambu Lab A1 Mini, I divided the wheel into two halves and added connectors, maintaining solidity and practicality in assembly. In this way, even those with a reduced print volume can easily create it, without sacrificing functionality.

🧩 Assembly

Assembling the wheel is quick and easy:

1. Print both halves of the wheel and the connectors included in the file.
2. Insert the connectors into the appropriate recesses of the two parts, paying attention to the correct direction.
3. Join the two halves of the wheel, pressing firmly until they click into place.

For an even more solid hold, you can:

• Add a drop of glue at the contact points.
• Or use a hot staple gun with metal clips (like those used for repairs on bumpers or plastics) to permanently weld the two halves together.

🔧 Recovery of the Original Hub

As shown in the picture, it is necessary to recover the central hub from the original wheel:

1. Carefully remove the hexagonal hub from the damaged or worn wheel.
2. Press it into the center of the newly printed wheel: the seat is shaped to perfectly accommodate it.

🛞 Final Stage

1. Mount the new wheel on the lawnmower like the original.
2. Replace the rim or external decorative cover, if present.

And you're done! Your new wheel for Parkside PMRA 20‑Li is ready to use 💪
