Hii, I'll show you how I tried to waste less filament in my multicolors prints, and convert part of the poop to something functional.

Fist of all, you are going to need a gun for glue sticks, and measure the diameter of the stick. In my case around 7mm of diameter

After that, you are going to need a multicolor print that you want to waste less filament, for example these voodo toy: https://makerworld.com/en/models/127942?from=recommend#profileId-143982

And we are going to include the model with the glue stick attached

We are going to check the size of the stick to be coincident with the diameter of our real stick, and the hight with the multicolor figure. Remember unmark the uniform scale:

You are going to check with the right button to the stick and mark the option to purgue in the object. Then multiply the number of sticks to waste less filament as poop:

And Finally you can print it and use it in your glue gun.

Additional notes:

• Not all the models of glue gun works fine for these porpouse. Some of them are limited in the amaunt of heat
• I use too for the final of the filament roll, if I only have like 5 meters or somethink
