The FDM file consists of
1) the two part frame, which is easily aligned; as per the photos
2) the lower four pack of rockets which has a solid mounting bar 2/3rd up; this rests on the assembled frame.
3) the upper four pack of rockets, which have two small “nubs”; these rest in frame of the lower rocket pack, so the top tier slightly protrudes above the lower rack. Please refer to the photos as a guide.
Please remove the supports from around the sights of the frame carefully. Test fit before gluing.
Printing notes: print at a fine setting (test prints were at 0.12mm on a Mk3S). Supports from the build plate are required. Depending on your printer settings, you may need “supports everywhere”; I have tried using “from the plate alone” and it was sufficient, but I can’t be sure it will work for all printer settings.
The resin model was printed on an EPAX X-1 with Elegoo standard grey.
