UPDATE: Here is a great solution for the filament guide..


So, I found this GREAT solution for using other brands of filament in my Dremel IdeaPrinter. Well, it served it's purpose, but had a few tweaks that I felt needed to be done. All of these things are work in progress, are they not?

Anyway - With permission, I reworked this:


By remodeling the idea, to reduce the load times, Changed the way that the spindles attached to the plate (one way, and no way to wear loose), and added a couple extra sizes of spindles. (Dremel Filament, Aspeteck, and WYZ brand). If someone has something that needs to be a little different, do not hesitate to let me know, and I will gladly create one for you.

It is also my understanding that this will work well with the Flashforge Dreamer, but I don't have one, so I cannot attest to that.

Anyway, I set the prints on more of a standard setting but to print a bit faster. I'm impatient that way. Needed to find some (8) M3 machine screws with (8) nuts/ (16) washers, etc. I tend to "over engineer" but the idea is to replace the existing vent (simple clip out) with a sandwich style plate, that won't change anything about your existing printer. No holes to drill, etc. Model is metric, so scale accordingly. The main plate should be 119mm x 139mm max.

The photos show pretty good on how to assemble the unit. Just set it all up and run the filament through the back grate of the printer and you are good to go. If you have any questions though, let me know. I will be happy to answer them.

Thanks! Enjoy!

Oh - I also included a bonus file - it's a little "chute" to run the filament from the side of the printer to the back, but I didn't like it much, so I don't use it. Maybe someone could come up with a better way of doing that. :)

Yes. This is exactly what I was looking for when I came to thingiverse today!!! Totally going to be my next print!


Very great design! I printed it out and assembled but the "other spool" is a way too short for my filaments from material4print. Could you add one with 0,5-1cm longer version of other spool? Also it would be great when you add the length of each spool to the file names.



I remix a lid and merge filament guide to use with your spool support.

Take a look:


FlashForge Dreamer Lid with Filament Guide

Thank very much for share this.

I printed in ABS using my FlashForge Dreamer and fit perfect. Pictures on "made" section.

So it's confirmed, fully compatible with FlashForge Dreamer.

Which of the spool pegs would fit Matterhackers filament? I just ordered some and would like to have my new spool holder all printed out before it gets here :)

Hey man.. It looks like (from the website) that it is one of the spools that has an "adapter" of sorts built into the spool...

So, my thought on that (because I haven't every bought any MatterHackers filament yet) would be to print the large spool peg. If you are low on filament, and just want to make sure that one will fit, go with the middle size. If the spool is a little large for the spindle, it should still work just fine. I just wouldn't put all of the weight on the small spindle. :)

Here are the dimensions in inches of the printed spindles.

0.73" = Small Size
1.13" = Medium Size
1.92" = Large Size

If you get it and none of the sizes work well for you, let me know the diameter, and I will gladly create a new pin to fit that brand of filament. Good luck man, let me know if you have any questions along the way.

Thanks so much! My best bet is to probably not be impatient. I can print out the new side panel pieces now and wait for my spools to arrive and measure just to be safe :D

I know the feeling man. :) Best of luck. :) Again - don't hesitate to let me know if none of them fit well enough. I will make a new one and add it to the set.

Spool just arrived and the hole is just shy of 2", printing out the large spindle and parts now. Thanks so much!

looks good. i'm sure the spool holder itself will print out faster then mine.

It was your original idea. :)

I didn't spend any time reducing the material use on the spindles, so the time it takes to print - probably makes up for it.

As you said earlier though - already going through some changes. Always something, isn't there.

Thanks for the kudos man and thanks for letting me remix this one.

I wish the filament could go trough the filament holder. would that work or would it disturb the print
anyways Great work

I'm working on a design that will bring the filament around the back of the machine (starting at the center of the spool) and back into the machine. Problem is, I am going to need to use a piece of tubing (just like the filament holder guide tube - just longer) to get it to work smoothly, and well - not able to print that part.

Still trying to come up with something that has very little resistance.

I haven't been using the filament holder on mine since I did this, and have had no issues with anything (aside from an occasional "spring unwind" from the spool. I'm hoping my new design will fix that.Currently, when you use it, the filament does "click" on some of the mechanics inside the device, but it's only the frame of the machine and nothing as far as moving parts. It's a little annoying to hear, but it causes no problems.

Hope that answers your question :)

this can be done on the dremel but not on the flash forge. on the dremel i removed the tube that came with the machine and just threaded it through one of the screw holes where fans are supposed to go. worked great. on a flash forge dreamer...there are 2 fans there. that's why i put the holes in the side of the case.

Thanks. Being my first ever post on ThingVerse, it means a lot. :-)
