I followed this visual guide which is for the same version (box) and using a similar electronic setup.
As I'm never one to completely follow instructions I skipped to the frame assembly first as it relies on the heavier tools and can be done independently of the other parts.
I couldn't find my countersink so just used a ~10mm drill bit in its place.
The L sections
Before you clamp them and get them in position mark the half way point on the board as this will help get the middle screw in the center.
In hindsight I would highly recommend you use clamps.
On the plus side 3mm filament is, well, 3mm so its ideal as a spacer for this job.
Note the drill battery sitting on the spacer to keep it level.
End of day 1
As I'm missing plastic parts there is nothing I can do for the time being.
Days build time: ~2 hours*
Total build time: ~2 hours
*Includes switching between 3 drill bits, sorting and arranging the parts.
Just a side note the frame appears much larger then I was expecting. I'll take a photo of it and the Prusa i3 frame side by side once I add the last piece.
