I finally got the time to assemble my custom Y/Z mod for my Simple! There are some design changes that could be made but I feel like this is a solid first try.
Now I just have to calibrate and print the parts for the X axis! 
EDIT: I have uploaded the files… http://repables.com/r/354 …Please bear in mind that I this is a work in progress. Complete notes are on the Repables posting.
Hi, are you going to share this mod? I’m interested on it!!
Indeed I will @David_Leal ! … I do have some changes that need to be made for durability and fitment. Once I get the next revision drawn, printed and tested I will upload all of it to Repables (with source files).
Interested. I’d be stoked if you share when you’re ready. Looks like nice work. Did you need to make any adjustments to get you’re Bowden working proper?
Thanks @Matthew_O_Reilly .
I will be uploading the files once I get things a little sturdier.
When I switched to bowden I only had to add about 2mm of retraction. I also use Cura, which is designed for Ultimaker, which uses bowden feed, so it’s pretty darn good with the basic settings.
Ok, i’m waiting you to print the pieces. Thanks
I posted the files at http://repables.com/r/354 … I don’t have much time right now to help with assembly instructions but if you complete this mod I would certainly appreciate any feedback.
