One of the problems I have in my shop is clutter collecting under workbenches and that includes the MFT/3 table which is evidently caused by entropy.  I decided to solve this problem, and resolve some other storage and functional objectives with the MFT/3.  These objectives are:
1. Eliminate clutter under table
2. Provide storage for several of the larger systainers.
3. Provide storage for 24" dovetail jig
4. Provide shop mobility and use as an outfeed table for other machinery in the shop
5. Improve table rigidity and permit use of the MFT as a workbench instead of just a table
6. Maintain ability to clamp vertical pieces on aluminum rail
7. Maintain ability to connect other MFT/3 tables in the future
8. Maintain ability to remove the MFT easily for use outside the shop

I used the Festool OF1400 router, LR32 drilling jig, Domino, and ETS150/3 sander.   The casters are Woodriver machine casters with leveling pads from Woodcraft.  These are as nearly identical to Zambus casters as you can get but less expensive.  The casework is from 3/4" birch ply which my local lumberyard calls chinaply.  This isn't a very high quality ply and has a lot of putty filling flaws on the face veneer but, it has a large number of plys similar to baltic birch and few core voids and costs under $30/sheet.  I used almost 2 sheets in this project.  Slides are full extension 350mm slides from Custom Service Hardware.  I also used Hettich VB36 cam fittings for the shelf also from CSH.  I used salvaged baltic birch ply from old cabinets in my shop and some leftover birch hardwood from other projects.  Magnetic tool holders were from Woodworkers Supply.  Total cost of materials for this project was just over $200.  Case construction is a combination of dados and rabbets with Dominos. 

This is still a work in progress as I haven't even applied finish.  I have used it on one project and it is extremely rigid.  I am unable to move it or rack it by pushing on it with all my weight.  I satisfied every objective with the exception of the ability to use as an outfeed table for my machines.  I can still recover this feature but I would have to remove the MFT legs and the 1/2" spacer shims on the ends.  This was my design flaw that I discovered only after the cabinet was assembled and discovered I needed the spacer shims because the legs on the MFT stick down below the aluminum corners.  I think I will order another MFT/3 to increase my table space.

How I elected to use the narrow space that would be pretty much useless for drawers.

Good suggestion Mettes.  I went out and checked but the legs on one end near the knobs stick down below the bottom of the aluminum corners so that won't work.  If I find that I don't need the portability much, I may just remove the legs which will grant easier access to the underside of the table and provide a good storage space for clamps.

Nice!  What a great idea for the side space.  I've been throwing my clamps in a small box in that space.  Your way is so much better.  I hope you don't mind if I shamelessly copy it. 

Cheers

Johnny,
The top of the cabinet is 738mm x 1145mm.  This size allows for a snug fit with no lateral movement yet easy to remove and install.  The other dimension you will need in the design is the distance from the top of the MFT to the aluminum corner it will rest on.  This dimension is 167mm.

I have done some further measurements and am only 5mm higher than my table saw.  I looked at the removing the legs and discovered there are nylon locknuts inside the handles which need to be removed to remove the legs.  I decided to not remove the legs and shims as restoring this would take longer than I would like so, have decided to get some 1/4" plate and shim my saw up.  Problem will then be resolved.

I like it! 

I really like the full-extension slides so that you can pull the systainer out enough to open the lid fully. 

I like the side clamp storage.  It's a good use of space...  BUT I have one small concern.  I'm wondering about the metals used in the clamps and the magnet bar.  If they are dissimilar metals, the slightest bit of moisture will cause rust.

Just my .00002 cents worth.

Steve - I stole this idea and expended it for a double MFT setup.  I took the legs off because I don't use the table outside of the shop.  The casters work great - I added 2 in the middle for a total of 6. Gliderites for the drawers.  This was my first build using all of my Festools and I learned a ton. The Domino is still a tricky beast when trying to line up the middle dividers. I messed up a few times but was able to salvage all the wood to make it work.  I'll probably sand and put a coat of poly on it at some point, but for right now, it's done and it's cleaned up the shop quite a bit.  Thanks for posting this.  It was a real help getting all of the measurements  right. FYI - the top of mine measures 738mm x 2300mm. This leaves about a 2mm gap in the middle of the two MFTs.

Hmmm. Didn't think of that but so far so good. I may be putting some rubber feet under the metal corners so when I'm pounding on stuff there isn't metal on cabinet impact.

very good idea ~!  i like it!
 [thumbs up]now im ready to copy your idea~~u have the cabinet's Drawings?
im lazy..

at 700 bucks building one is tempting,I'm  looking at the whole picture.wood vs metal,ten to twenty times stronger for the same weight.cost of materials is about half,with no locks.labor to build, and finish vs more money.am I going to do as good of job,yeah but at how much more labor.my ego says build it, my wallet says buy it.then the first one will morph on down the line till I have five different,four I would no longer want ,but not get rid of because they would function.the more I think about it the harder the choice is

Thanks for the compliment.  I must confess that the vertical pullouts with magnetic strips have been my least favorite part of the whole assembly.  I just put it there because the space wasn't usable for much of anything else.  After almost 2 years of use, if I were to do this again, I would just make a recessed area on the end of the cart for clamp storage foregoing the pullouts.
