Thank you for that. Here is the link to the IPT file there for anyone who wants it. There will be several more parts and changes in the next few days. http://cloud.itsolutionnc.com/public.ph ... c66248a7f8

I'll also be upluading the DXF file for the metal backplate sometime later today.

Parts that are still pending design:
1. The X carriage lower mount adaptor
2. The X carriage upper mount adaptor
3. backplate
4. Optional X axis cable chain adaptor
5. Optional Z axis cable chain adaptor

Here are the files for the metal backplate attempt. Same file, different formats.

X Carriage adaptor plate. This will allow you to mount existing Lulzbot Taz style toolheads to the Openbuilds X carriage plate. It requires 3mm heat set inserts. You will also need to reuse or print the X carriage guide plate (http://download.lulzbot.com/TAZ/5.0_0.5 ... age_guide/)

Here is the printed version of the tool head mount. I am probably going to move the mounting bolt location slightly inboard to allow for easier assembly, so I'll post that STL once it's done, but here is the general idea. This uses the stock Lulzbot toolhead mount retainer thingy.

Also, truly awesome forumite cnr0616 (Aka Craig) has access to a laser cutter and was able to cut the backplate piece out of Aluminum plate for me. I You can see the belt mount nubs, those will probably get thinner aluminum pipe covers and smaller washers, but they are plenty solid as is. Both ends of the belt anchor there, then the belt adjuster is on the Idler pulley side. The whole assembly is absolutely rock solid, no play or wobble at all, smooth as butter, and shiny to boot!

I can't say enough good things about cnr0616 though, Thank you again!

I'll probably get the actual rail mounted sometime this weekend and start trying it out. There will also be an auto leveling mount for this as well still to come.

New parts today. I'm getting ready to actually bolt the assembly onto the machine, and I decided I wanted to try to reinforce the motor mount a bit more by adding M5 heat set inserts in place of the M3 inserts. I think that will be much more survivable long term. I also redid the mount platform to move the screw holes over slightly to make mounting easier.

Alright, back from my weeklong training class, finally got this bolted on. Here's a quick video of it in action. More pictures, assembly instructions etc. to come.
