I was flipping through new messages over on SimHQ’s cockpit builder forum and someone had posted a link to this model: https://grabcad.com/library/kg-13-flight-control-grip-1

I downloaded it and converted the part files to STL and threw it at my SeeMeCNC Artemis 300 printer.  The results are below!

The model feels really good in my hand and will likely be the core of the Bf-109K4’s grip.  I’ve got some tweaks to do in order to install switches, etc. but it’s a great start!
