Structures for Ork guard towers, front gate and two fence types (X and L shapes, based on side views.).

Towers are basic supports and roof, same with the fences. The basic concept is, build the frame, stick random armoured plates on them for protection and structural supports.

The walkway goes between two towers, random plates are used for the floor. The front gate also is attached to a tower at each end, and more plates stuck on. (Sorry, forgot to take photos.)

I based all my fences and towers on MDF and flocked to match the other terrain for my Ork table.

07/05/2021 Update: I took the terrain along to the games club, as we have some nice Orky themed game mats... Set all the terrain up, took some pics, got all 129 orks out ready for battle.. and my opponent DNS'd.. Oh well.

Also, these were printed in 0.2 layer height, on a barely working Witbox 2... before I got my much better Ender 3 Pro, so they look crap in photos.

I will take some pics of the gate when I get round to it. I will also finish painting them past the current basic colours when I get round to it...
