Thanks all for looking.  

I do crap on a tad... ok 

however, the intention is not as much to convince others to make puzzles (have just about given up on that), but moreso to maybe give ideas or a glimpse at a tool/feature some may not have seen.

Don't undersell yourself BB1 (I've seen your work)... puzzles are not everyone's cuppa tea, however, rather than for yourself, there are many recipients that love them as presents (free or sold).... talking about sold!  Though the effort is never/seldom returned... but that's woodworking.

Splinter, (whispering so the MDF gods don't hear) I prefer the look of solids and I'm hoping that the sizes give them a hall pass for stability... and while I still cut the box on the laser, it's the preparation to a consistent thickness that is a pain.
The beauty of MDF is that I can churn off any number of copies and glue them up in the comfort of my office on my portable mini-workbech... for freebies, that is the economy.
When I tell/show visitors of the work involved, they confirm I'm crazy,
 

 
JJ, I remember making a post about my increasing puzzle menagerie, I think I labelled it as "Rabbit...".
