The electronics and arm have been fitted, so all the threaded inserts lined up as they should. You can see the heat sink I produced for the regulator, this stands on 4mm brass pillars. The PCB is on 15mm x 8mm dia Nylon pillars, you can see the harness has been soldered direct to the connector pins at bottom right, the PCB can be removed with the leads still attached as the cable entry slot has been made large enough for the multi-pin connectors that attach to the PSU to fit through. The right corner of the board tucks under the plinths top aperture, there is just enough room to access the fixing screw. Because I modelled the whole deck on a CAD package I was able to plan this level of detail before any work was started. If you look at the block the arm is sitting on, its right hand face lines up exactly with the top edge of the chamfer in the plinth, just as it does in the earlier CAD rendering of the proposed deck. Working with a 3D CAD model shows up the design issues before you make the parts, so you can tweak the design in advance. For instance, its no coincidence that the pillars for the PCB are exactly 15mm tall which is a standard size for off the shelf parts, I tweaked the assembly to create that height and also so I could use standard multiples of plywood for the plinth, avoiding unnecessary machining. I downloaded the CAD package which is a trimmed down student version, but it still has some reasonable functionality and most importantly was free.
