Thanks Mark, that's the main reason I have been making these things. Mostly just to improve my skills in design but much more helpful with real life goal in mind.

Pretty sweet! You're getting that 3D printing skill-set "rollin-on".

A little more to this one compared to my normal creations, I have made a small test box for Hawker 900XP Fire bottle Squib Test. Much better than sitting in the hole with a meter or having lights and wires hanging down. Lights plug into the side and then stored in the box when not in use. I made the harness from box to the squib plug to be around 10ft, would suggest using a hanger to support the wire bundle when inside the aircraft so the weight of the harness doesn't pull the cannon plugs. On my harness I am just using pins but next time I do the check I plan to get measurements to 3d print an insert or find a cheaper alternate plug that can work. Alternatively you could just buy the plug called out in WDM but they are pricey. While this tool wont change your life hopefully it can make a crap job slightly better.

Total print time around 8 hours
Total cost plastic and parts excluding wire harness $8

You will need
BA9S socket x4
8 pin connector male and female x1 (cannon plug I used is 18.5mm flange size GX16 8pin)
Lamp 1495 x4
Lamp 313 with locking tabs ground off x2
4mm diameter magnet x 8 (optional)

Still needs sanding and maybe some paint
 

And, then again.... It doesn't matter what system is installed, this won't work very well!!
  
     
 

I was also unable to find the exact definition, I found it in a 747 task card index. It's list the possible skills as (Airpl, ENGIN,AVION,ELECT,SHOPS) So I guess that it means airplane and used whenever one of the other definitions does not fit.

There is no preamble to the task cards in the front matter section. I guessed it is abbreviation of "airplane" and it means skill which is related to airframe and system that excludes avionics and electrical system and engine and APU. However what surprised me is that it is assigned to general visual inspection of EWIS.??!!

I've asked around (even the heavy check guys), no one seems to know what that means. Is there any type of preamble to those work cards? A lot of acronyms are explained there.
