I have a 1998 xt225 and I’ve been trying for months every night to find the missing side panel I need for the bike does anyone have one available or 3D printed one I’ve seen the cad file online for it. Any help would be greatly appreciated

If you have a good 3D model file like an STL there are 3D Online Services that will print parts. Know that part won't be easy to print owing to its shape. If you provide the link to the CAD file, I can take a look at it. It needs to be an STL file which is pretty standard. If it's a native SolidWorks or Pro-E format I can't open it. OEM panels are very hard to come by now. These were injection molded from polypropylene as I recall.

I can open the solidworks file if that's what it is. Buddy of mine uses it all day long, would just have him open the file and see if he can export to stl. Or, just find a company online that will produce parts from the solidworks file directly.

Solidworks can import/export several file types. Sometimes things can get lost in translation when doing that, especially with assemblies, but simply converting to an .stl should be pretty straightforward. It might need to go to a step or iges file first, but I don't think so.

A 3D printer uses slicing software. I've got a Prusa i3 MK3 which is too small for printing a side panel. It's what the slicer is comfortable importing that matters. PrusaSlicer is what I use which imports STL files fine. It will accept IGES and STEP but I've never needed to stray from STL. Larger curved unsupported surfaces are going to present challenges. Parts are printing on a flat heat bed via slices of extruded plastic beads built up in layers. You can't lay a bead down in thin air, there needs to be something to support the melted plastic. Slicers can detect this and include supports but there are limits. Texture is another factor. Printed plastic parts won't be smooth like an injection molded part. You'll see the bead lines as the layers are built up. Modeling the part in another challenge. Some require scanning equipment and software to get an accurate rendering. 3D printing plastic is tricky and not just pushing the button and walking away.

If someone went to the trouble to model that panel, they likely would have printed it. It would be good to see the results. If demand is high enough, some companies will do repro parts from injection molds. Good luck.
