Modular Synth Panels

Hi all,

New member here. I have a large Dotcom format modular synth and I'm interested in getting a Synthacon filter module, especially one that has the "All In" input in addition to the LP/BP/HP inputs. Like this one, but in a Dotcom format:

I also found this link, which looks like someone else may have already done exactly what I'm hoping to do:

Anybody know about this? 

I have a good amount of experience with electronic kits but almost none with custom front panels so if someone else has already tackled this I'd appreciate any assistance.

Thanks!!
