Here's a greeblie I've been working on for awhile now that goes on the backwall opposite the seating area towards the front. I've attempted to make it as accurate as possible to the ESB version of that wall. It should glue directly on the wall 15mm in from the small end and 5mm from the bottom of the wall for perfect placement. There is a hose that goes from the center circular hole to the vertical greeble to the right of it. Can be simulated with a piece of wire (wires don't print well). Also the cutout thru the whole part should actually be cut in the wall behind it, starting 5mm from the bottom, 2.5mm wide, and extending up the wall approx 35.5mm! You can use the vertical cutout as a guide for placement. I suggest gluing a piece of styrene behind the cutout for optimal look. I hope you all like this one. Lemme know what you think. NOTE: I've added a couple of photos of the wall with the greeblie in the proper position (the rendering depicts it sideways, it's suppose to be 90 degrees upo and down).
