Project: Spool Holder (ver. 1)

We started this project to come up with a better spool holder that would not sag.

To prevent the spool holder from sagging, our idea is to support the spool at at the bottom rather than from the side. We use ball bearings to reduce the friction.

Side View

This is the side view of the spool holder. It consists of the base, which holds two clips for the ball bearings. We designed an initial version in Sketchup and printed it to see what changes we need to make. Continue reading Project: Spool Holder (ver. 1)

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:

Introducing the Flashforge Dreamer

So I heard you are thinking of buying a 3D printer. The options out there can be dizzying, but once you have a clear idea of what you want to have in your first 3D printer, the selection process becomes much easier. I eventually settled on the Flashforge Dreamer, made by Flashforge in Zhejiang, China. This is almost the exact same printer that Dremel is using as their 3D Idea Builder. This printer is available from Simplifi3D, a vendor based in Bras Basah, tucked into a corner on the second floor.

In this post, I will outline some of the deciding criteria that I used to narrow down my choices. Continue reading Introducing the Flashforge Dreamer
