MDF Tool Layout Organizer - Alternative to Kaizen Foam

If you've never worked with Kaizen foam board to organize your tools, you'll likely think the below approach is a waste of time or likely that I've lost my mind.  Make no mistake that this approach takes some time to implement, yet the results will leave you with a dense quality storage solution on the cheap and lending itself fairly well to accommodate changes in the future.
Now about a year ago I had great plans to implement Kaizen foam throughout my shop to help organize things.  Ran out and purchased three 2'x4' sheets of foam at thicknesses of 20/30/57 mm costing about $11/$13/$25 respectively.  My first attempt went fairly well as pictured below but the effort which was required and fair amount of frustration in trying to make the project look presentable left me without the desire to take on more ambitious projects with Kaizen.

Which brings me to my present tool organization approach, "MDF Layout Board".  Of course you'll need a CNC router to tackle this type of project not to mention a desire to shore up your CAD skills (which I was in need of).  The process of course is to measure and create a CAD file for each and every tool you'd like to place into the board.  After that, a separate CAD file is required representing the tool perimeter geometry with a bit extra clearance, and then set out to organize the layout.  The below picture shows my previous storage solution which is to simply keep the tools inside the manufacture cases.  Although it's a pain to access the tools, they are kept safe from damage .... just take up a LOT of drawer real estate.

Now below you can see the MDF board in action.... holding twice the previous drawer solution afforded me.  It's a pure joy to open this drawer up and quickly access tools from a secure storage space.

Cost using MDF is actually cheaper than Kaizen by about 40%.... with a 18"x25" of Kaizen running $5 and MDF coming in at $3. 
​I've got a second drawer I'm slowly putting together.... work in progress shown below.  Can't wait to get these expensive items into a nice secure layout board!!

And below is the final chosen layout and results.  This drawer is 3" deep to accommodate some of the larger tools so is uses three layers of 3/4" MDF with small 1/2" feet underneath.
