the question is how big do you want it to be?
any model could be upscaled to what ever u want, but might need some updating on the model too, so if u dont have any cad(computer aided design, e.g. fusion360) experience, that would be a problem too.
even a good simple 3d printer costs today 150 bucks
plus the material needed lets assum 5 rolls of fillament(the material), thats another 5*25=125 bucks
and for a proper 3d model, u need the model it self, wich cost another 50 bucks
and the printing time is aproximatelly 2 weeks or 2 months, depending on the size, and in this time u can't go shopping or bowling, u have a runing machine thats needs to be supervised all the time.
on the other hand,
the Revell 1/29 Xwing is 435mm long it costs around 120 euro on amazon
the revell is a injection molded model (almost finished), but the 3d print will have "lines" alot of lines, that need to be sanded and "putted" till your arms break off...
u can check "cgtrader" or "gambody" for reaseonable models, sometimes "thingyverse" also has some good models
thingy has a 1/24 for free
SketchUp is no longer free,so will be converting files to Blender, and also try to convert polygons into quads.For Resin Printer, I have uploaded optimized version of X-Wing.https://www.thingiverse.com/thing:6397525some people say front bottom fuselage file has some problem.just download that...

yes its for free, i also have a 3d printer, but i choose the revell one
i dont want to scare u, but if u desice for the print, u need
* time
* money
* protection(breathing mask for sanding and other things)
* cad
* more time
* adjusting the machine
* patience
* handcrafting skills
