So, i need to make a 3d print of my project in blender, but they're is some kind of problem in my file that i don't understand, i asked somebody in a 3d printing store in my city but even him could not help me.
i'm just beginning with the program so maybe i did something wrong creating the object, and i know nothing about 3d printing aha..
i've been told that i have holes in my mesh but i can not find any, or maybe doing it wrong
Can somebody have a check ?
Thankyou Carlo, now i understand the significance of manifold and watertight.
Unfortunately, i did not manage to fix the problem... I try a lot of different ways to fix it but did not get lucky. and i don't have the version 2.80 blender to use the new tool. i have tried many tied; delete and reconstruct some part and reconnect in many ways..
