Summary Should accept any single battery clockworks. Designed in sections so you don't have to be at your machine all day, like the Seahorse Clock. Print a piece at a time, and assemble later. Printed using 4 shells, 3 tops, 2 bottoms, 10 percent infill. No support required. Finished model was glued together after painting. Note: Do not remember where I got this model and can't find on this site. If it is yours, let me know for credit...
