The T249 is very interesting and I've always wanted to build one, but for lack of a kit have never been able to.
But what timing! Arriving with my latest "bag of stuff from China" includes a model of one of these I have bought from a seller I've never bought from before. This will likely be my next project.
The details appear there at first glance, but it is not easy to judge the details on a white, very slightly translucent model. The print quality (looks like it was made with a high-speed industrial printer) is not at the same level as plastic molds or slower at-home resin printers and it arrived with broken bits, but I am sure I can make it work.
It is very small compared to the M48 - certainly it is only slightly longer than a M113, on whose chassis it is based on.
Arriving with this is a set of 3D printed tracks, from a guy I believe I've bought from before a year or so ago, but it seems their materials and processes have changed; the parts are warped and I am not sure I will be able to make a full set of tracks out of what I can salvage.
In the meantime, I have added some additional details to the turrets - handles and the such. I also used some 3D-decal weld beads.
