I printed this on my Monoprice Mini V2. Everything fit at 100%, except the spring barrel, which I had to print a 99%, but it works fine. I did need to change my bed size to 124mm x 124mm to get it to work though. I also had to turn off skirts for a few of the larger pieces because I didn't have the room.
Mine went together fine. I couldn't find any M3x25mm screws locally, so I used a #4-40 x 1" screw and nut that I got from Lowes. Lowes also didn't have any M4x16mm screws for the base, so I used 20mm screws instead. Lowes does stock those screws, but both stores I went to were out. Other than that, Lowes had all of the fasteners I needed. If you want to save a few bucks, just use longer screws where you can. I used a 40mm screw instead of a 25mm screw to go through the hairspring assembly and it works fine, just sticks out a little bit on the end.
Mine worked fine almost right away with very little tweaking. The only issue I had was that the brackets that connect the bases were not level for some reason, so the one end where the hairspring assembly is was lifted up a mm or so. When I manually held it down to the table and made it perfectly flat, it ticked perfectly. I think I had a slight elephant's foot on each of the brackets that was causing the issue. I just filed down the bracket where each base piece sits and it seemed to fix the problem. I get about 2 minutes run time, which is plenty, IMO.
I did print the following remixed piece though, which I think helped:
