About this 3D model

I had a request to create an X-end that would accommodate a nema 17. I figured I would revisit this design in hopes of improving it. I borrowed the SOLDOODLE 2 COMPLETE by Incredibert for a more accurate 3D model. note this X-end setup will work with stock solidoodle X carriage. please leave comments to any improvements I can make to this setup. also I have attached many different file types in hope the community will take this 3D Model and make improvements and modify it. if you make changes to the model please leave a pic and share it. Thanks to all those that have had positive feedback as I believe positive energy produces positive outcomes.
