Horizontal spool holder

[chrisash]

I had assumed that supports "ON" in the slicer would overcome the overhang, myself i have not come across the thread twist problem , so just a idea and not much use to me apart from improving my understanding of fusion

My experience recently in printing model parts is that it's best to avoid using supports as much as possible. I lost detail on virtually every part that used supports and it created a lot of work filling and sanding the affected parts.

You could do it with a lot of supports but better if you can design it out.

What about printing this stand in 3 components that clip together? There's your problem "engineered out".

I have to admit that getting a design that prints out easily on the  is something that I have yet to master and get right every time. Separating into components is often the best solution. Tip - Super glue works well on pla.

I recently printed and made a model of the Liberator from Blakes 7 (something I've wanted for a very long time), it's a complex shape but the designer had separated it into components that when printed didn't require supports, and provision was made to use pins to join components.  That is how any 3D printed design should be done and yes, superglue (and epoxy) work well on PLA.

From my small knowledge so far, the difference in size can be a problem with shrinkage for larger models

I thought i would make a simple sample size spool of the filaments and used a central tube of 50mm with a thread on the end plus a nut the same size 50mm, (typical of the centres of most spools)

When i printed both parts out the measurement between the outside of the tube thread was 48.8mm and the inside thread diameter was 46.2mm, both using the same PLA

Whilst you can scale up/down a sample , doing things 2 or 3 times is a bit of a pain, and the shrinkage does not appear to be something you can make a graph of to eliminate the problem very accurately, though still learning and  new to printing , i guess others may have found a solution or used better filaments
