Filament storage and roller in one

This model was nice but I got really tired of the nuts moving on the threads. I created a new, easier model. https://www.printables.com/model/364323-versatile-spool-holder-system

When printing multiple filaments, I need to move the desired filament spools to the printer. Why not make a storage system at the printer and use the filaments at will.

This project contains several printed parts:

• 2 different parts for the rolls
• 1 type of spacer
• 1 type of stand

2 files: 1 file for the 2 ends of the system (left and right). For each system you need to print this file 1x. The other file is needed for each extra spool in the system. So in case of 8 spools you need 1x the file with end parts and 7 times the file with middle parts.

Extra needed:

For each system M8 thread as long as you can get/want/place.

For each spool 4 bearings size 8x22x7 (inner diameter 8mm, outer diameter 22mm, width 7mm). 

Several M8 nuts (for the end parts 8 in total, for each extra spool you need 4)

Optional M8 washers (same amount as the rolls)

----------------------------------------------

When assembled the spools will sit rather close together They have approximately 1cm distance between them.

Since this system uses M8 threads, you can place the rolls at any distance you want depending on the width of your spools.

-------------------------------------------

Assembly:

Press the bearings in between 2 different roller parts. You should hear a click when the 2 printed parts (with bearing in between) are pressed together.

At the end of the entire assembly you need (from the end of the M8 thread): 1 M8 nut, 1 stand, one assembled roll, one stand, one nut. Repeat this for the other end of the currently used stands.

At the middle parts (between 2 spools) you need: 1 M8 nut, 1 stand, 1 roll, 1 spacer, 1 roll, 1 stand, 1 M8 nut.

------------------------------------------

At the moment of publishing I have just finished one set of middle parts. No M8 thread or nuts used at this moment, photo's are just to show the end part and the middle part.

Assembled pictures will follow later on.
