I really don't think the technical work required to build this unit, provided you had all parts on hand, is really that advanced.
With V3.1 it will require moderate modding skills.
Cleaning up of printed parts
(there is left over loose material in nooks and crannies)
Coating of external printed parts
(the plastic is porous so at minimum several applications of clear top coat on external parts)
Some hand sizing of printed parts
(this will vary from batch to batch as the 3D printing process isn't consistent on tight tolerances and finish)
Drilling and grinding of SS screw
(this is probably the most difficult part unless you have a drill press or lathe and a little experience at it)
Soldering
(If you have never soldered I would suggest some online research and practicing soldering first)
Gluing (I use CA)
Did I miss or misrepresent anything fellow beta's?
BTW, be aware that the colored plastics are not subtle.
The "Coral Red" (Now just called "Red") I chose sticks out like a sore thumb.
Now, making the CAD drawings and getting precise measurements/angles, placement, etc, that's where all the wizardry comes in.
Agreed
