Original Bamboo lab Makerworld MH006 Jet Engine Creative Model Components-Engine Aircraft 3D Printed DIY Parts Compatible with Bambulab P1P/P1S,A1,X1/X1C/X1E-Prints NOT Included-NOT for A1 Mini

At first, I wanted sealed metal bearing, ya know, for longevity. I am glad I chose these instead since the open style bearings roll really easily and make the jet engine fun to play around with.The fasteners are small, but exactly what is supposed to be used with the parts if you print using the standard .stl files.Helpful tip: put a small piece of tape on one side of an open wrench. Place the nut in the jaws of the wrench and against the tape so you can get the screw started in those tight spots. This helped keep me from dropping the nuts all day long.

Got 4 kits have two almost built. Hope they work.

This is the original parts from Bambu Labs to create the Jet Engine. All parts needed are included in the box all you have to do is 3d print the model itself and use the included screws/washer,etc to put it together. Very easy and looks fantastic!
