HI Roxy,

I can't get it to upload to Thingiverse for some reason. I've attached it.

Sorry for the delay...

Steve, I'm intrigued by the buss you have at the top or your printer. That's an interesting solution for swapping out parts. Does it work well?

I found some Nema 14 in canada here

That looks about right. It's a little less torque than the Pololu motor. Let us know how it works.

I do not do ebay, can I arrange to buy one directly from you?

I'll PM you and we can set it up.

Inland Brand from Micro Center a block from My house and it prints amazing (same suppler as Prototype "eSun")

The terminal strip across the top is great for the 50+ crowd with tired eyes..It works great for swapping components and troubleshooting.

I've make another modification to the NEMA-17 version. It was done in CAD so you can download the .sat version and modify it. I posted a .stl too if you just want to try printing it. It will need a small amount of support on the horizontal motor mounts.
