Very simple way to convert any stl file, image or huerforged file into a clock, you have 2 different ways to do it.

1. Add the file you want to transform, scale it and fit inside the numbers of the clock, only scaling the model. You can print separately the numbers and the clock body to give them a texturized appearance, carbon fiber, fantasy, smooth..……… and posteriorly mount them or print directly the body with the numbers choosing the colors you want.
2. Add the file you want to transform, scale it and add the “clock numbers” as a negative part. Be sure the negative file is a 250x250mm square. Then you may print de body with the numbers choosing the colors you want. Is very important to adjust correctly the negative part to avoid the purgue zone of the bed, It would be necessary to cut the file you want to transform to eliminate the part wich is over the purgue zone.
