EIBOS Cyclopes Extension Walls and Bearing Risers - 1 Part with threads for Bowden Couplers

The original model was split in 2 parts, which is not necessary, if you have a 300mm printbed. Also, the original is a little too short, so that the eibos lid fits only with force. I added 1mm of length and chamfered the top part. Lastly, I inserted 2x M10 threads into the wall to remove the need of a filament feedthrough through the lid. This way you can remove the lid without problems. You have to print the bearing risers from the original model to make it functional.
