Dreame A1 Spike wheels v3

With this new wheel design, you can minimize wheel slippage for your Dreame A1.The smart wheelcaps allow you to add weights inside the wheel for better traction and stability.No modifications are needed to your robot – these wheels fit directly onto the axle.Note that the fit is tight, but it does work.If you print with a layer height larger than 0.12 mm (as specified in the print profile), the threads may not function correctly.Minor support needed (in wheel center and in the cap handle) I hope
