Very bad model, too thin, loose and the wheels fall out.

@P3D_CZ Thank you for the review.
I have published the CAD source link in the description. Would it be possible for you to help me improve the model?
I'm new to mechanical engienering, is there an X-Y version of this mechanism
@sternli27 i have no idea what it would look like. i am trying to place a mirror with high precision using XY translation, what mechanism could i use?
@VanushVaswan_1908343 you could try something like this:
 https://www.printables.com/model/886997-fully-printed-linear-stage-with-anti-backlash
or
 https://www.printables.com/model/903033-two-axis-printed-linear-stage
but if you want to have high precision you might need something out of metal

Printed with MMU and Paint-On colors.
Thanks for this model. Looks nice. Works fine.
@Tritschi very nice! Great idea with two colors, thanks for sharing :)
