Just a quick model of a traditional Finland clock from game called My Summer Car.
Designed to fit standard quartz clock mechanism (56 x 56 mm). You may need to adjust your standard clock arms to make them proper length, i might later try to model proper printable ones! Printing this with Prusa took about 2 hours and 40 grams of filament was used. Total cost of project with cheap eBay quartz mechanism will be less than 3€
Woodfill PLA will look authentic and awesome to the style! i printed it without skirt, rafts and supports using black PLA that i happen to have. No cleanup needed, just add mechanism and hands. You need about 220mm printing area to print this clock.
After printing, all you need to too is attach clock mechanism. Mechanism i happen to have had no locking screw so i just used few drops of CA to attach mechanism to frame. After that, just insert arms, set time, and put it in your favourite spot for everyone to enjoy!
