Building R2-D2 - Part 5: Body Assembly including dome drive.

Welcome to Part 5 of my Building R2-D2 series. Today we are building the main body, fitting the utility arms and getting the dome drive working.
I'll give a few tips along the way that will hopefully save you from making some of the mistakes I've made (so far).

I'm using the Mr. Baddeley MK 3 cut version files for the body. My little Sovol SV01 with a build plate size of 280x240 was just large enough for some of these larger body files which are the biggest in this entire project. A few used up the full diagonal space on the build plate and almost all the gantry height of this printer. (300mm).

Hardware needed for the Baddeley MK3 3D printed R2 body (will obviously vary slightly feature & mounting methods dependent):

- 4x 5/32nd rod (threaded on ends) or (M4 threaded rod) 500mm long
- 4x 5/32nd rod (threaded on ends) or (M4 threaded rod) 370mm long
- 2.5mm steel or brass rod for making the door hinge pins (I just used some plain smooth finishing nails of the correct diameter I had in my nail bin)
- M2 (2.2mm) self tapping counter sunk screws (for doors/hinges). I used assorted set - lengths from 5mm to 8mm)
- 12x M6x35mm button head hex bolts for skirt
- 12x M6 hex nuts
- 12x M6 washers
- 4x M4x30 button head hex bolts
- 8x M4x12 button head hex bolts
- 20x M4x10 button head hex bolts
- 30x M4 square nuts
- 10x M4 hex nuts
- 3x M4 x30 counter sunk hex bolts for lazy suzan to dome fitment
- 6x M4x15 hex bolts for attaching lazy suzan to body ring
- 4x 606 ball bearings for utility arms (your call if want to use RS/sealed, or ZZ cover types)
- 2x 5mmx5mm magnets for doors if you want magnetic door catch (instructions call for one 5mm and one 3mm. I found the 3mm magnet too weak so used both 5mm (drilled 3mm door magnet hole out larger).
- magnets of your choice (if any) to secure dome to lazy susan.
