Problems: Sagging spool holder

Did you know that the Flashforge Dreamer doesn’t actually come with spool holders? There are two cavities, one on the left and the other on the right, in which the filament spools sit. But there are a bunch of designs for spool holders that can be printed to fit spools of various sizes. Our vendor, Simplifi3D, was kind to provide us with a set of two holders to start with.

One of the first problems we encountered while printing: the spool holder actually sags after some time:

This is a problem because when the spool slips to the end of the holder, it comes right under the edge of the build platform:

When the platform comes down after printing is complete … loud and scary sounds ensue!

For the time being we have to be vigilant and quickly push the spool back once the printing is complete. Instead of whining about it, we can turn it into a learning experience instead. So here’s a first task for the research team: design a better spool holder.

You will see some posts from them in the next few days detailing their plans for an improved spool holder that is not only easier to use, but more stable as well. Stay tuned!

[Edit] Here is our first attempt at an alternative spool holder.
