About this 3D model

I have created based on other models of supports, a support based on two columns and a piece to make guide of the filament, also I designed ceilings so that the tube does not leave the guide. It is designed to use a 16 mm tube. This is done thinking of placing 3 rolls of different colors, which is what I usually have. I hope it can be helpful. It's for a Geeetech Pro B
