IASorensen Hello Artur,
Thank you so much for contacting me and also for sharing your feedback. Based on your comments I have revised the design for the elevation part and have offered it for sale with no markup. As soon as I can, I will upgrade the rest of the related files with the new elevation part in the hopes that it makes installation easier. Also, I would love to see your Chimera with the upgrade parts on it once you are finished building.
Have a great weekend,
