Generic Drafting Glass Table includes 85 pieces and a parented parts version so you can easily put it in any position you want. It was made in blender 2.8x and includes basic pbr materials. It includes FBX and OBJ files.
Materials are compatible with cycles and values are based on a similar real life variant of mateirals.
Update, V2 Files include the pen holders on the sides that can be seen on the preview video.
The real life version of the table can be used as a desktop since it is not as tall as other drafting tables, it also has a really resistant glass, it doest have colored glass as other tables because it is intended to be used with 3rd party lights below it for easily transcribe and sketching.
