Shaper Origin Flush MFT Hold-Down Clamps

I use the Shaper Station for 90% of my Shaper Origin projects. The clamps used to hold it down to my MFT seem to always catch power cords/hoses/my arm, etc. (I have my MFT mounted on a mobile table, so there's not much room below it to come up from underneath.) So, I decided to try to come up with a flush clamping method. I settled on this. The clamp has a form fitted (.5mm clearance) set of slots for the legs of the station. I had already created threaded (8-1.25mm) star dogs that come up from the bottom to hold down my vacuum pads, so I reused them. I printed the bolts so I could have the 4mm hex slot in the top to fit the Shaper hex tool. I'm really happy with the hold. 

I printed these with added strength. The slicer screen shots show the settings. I also rotated the bolt 90° with the flat side down. By leaving the side flat, it can print in the strongest orientation. The supports do not affect the thread. 

The threads on the dog, which comes up from below, are tight off the printer. I either use a warmed 8 1.25mm bolt to loosen them, or, better, use my tap and die set to cut the threads deeper. The latter allows me to use my 3D printed bolts, which thread in nicely. If you don't have a way to increase the printed thread, you may want to stick with real socket-head bolts. I've included a link to McMaster Carr, which has several options. Also, if you would rather use a stronger material for the dogs, Veritas has a set of dogs that will work. 

I printed mine in PLA, and found that if I tighten the bolts down with the hex tool that comes with the Shaper Origin, it will strip the hole after a while. So, I just use the hex tool to hold the bolt stead, and use the star on the dog to tighten everything down. Works like a charm.

At the request of another user I've uploaded my Fusion 360 file. I cobbled this together quickly using other models I've designed, and didn't go back and apply my best practices...fully parameterized with all features and bodies properly named. But if it helps someone else out, feel free to download. Just please don't judge. This is not my typical work.
