Lockpicking practice stands…

I’ve been tempted to buy a few of these, but I’m disappointed that it only holds three cylinders.  I’d love to have one of these (or FOUR of these, preferably) that would hold five cylinders.

I built a trainer last year for five cylinders, but I built it with full deadbolts with the KIK (key-in-knob) cylinders installed into them, so it’s a bit heavy and unwieldy for portable use, especially if I had to lug around four or five of them.  

If anyone has the capability to design a 3d model of something like this, please hit me up at [email protected].

Requirements: 
* Five evenly spaced openings to fit KIK cylinders
* Each opening should have a tension screw below it with a thumb tightener, to snug the cylinder and keep it from slipping
* A nice wide base with four holes near the corners, so that it can be screwed to a block of wood or other heavier object and prevent tipping.

Update: Found the TOOOL Practice Lock Case by MikeyMakesIt, which would suit my needs wonderfully AND be even more portable, but the big players want like $50-60+ just for the bottom piece.  Somehow I feel like this should be a lot cheaper than that.

And then there’s the Locksport 5×3, which I wish I had the STL for.
