Replicator 2 Top Mount Filament Spool Holder/Dispenser by brackett27 Apr 15, 2013


I got tired of tripping over spools of filament in my office. I borrowed the concept from a design I saw (http://www.thingiverse.com/thing:51635) but made it lighter and faster to print. And prettier too. :)

The rod is a SS 3/8in 24in long. (you can get rods and nuts from Home Depot/Lowes etc. or online at McMaster.com)

I simulated the tower in Solidworks (files attached) and it should be able to hold up to ~100lbs total between the two towers.

I recently added a second tier to mine and it works great tool (http://www.thingiverse.com/thing:94691)

I found the M6 x 20 were too long and required a 2mm washer (which i printed) to keep everything tight.

I printed this and have been using it for a few weeks now. It is rock solid and has no trouble holding 5 spools of filament. Great job!

Print a left and right of each tower. You will have to orient it tabs down on your build plate.

The towers come with tabs on them to prevent curl. You will need to cut/snap them off. I found I needed to use dykes to do it. I used 5 shells, 10% infill, 0.34mm height.

I printed some spindles so the spools roll better on the threaded rod (the red bits). I printed them five on a plate, you can too. I printed them in the vertical so you will need to flip accordingly too.

First off, thank you for this great design, I've finished printing and about to attach. I am finding though that the bolts are not long enough to reach the internal threads with the added tower. Did you have to get longer ones?

Wow, yes, I found a couple M6 - 1.00 x 20 Screws that fit perfectly. What is even better is that they have the hex bolts and look exactly like the original Makerbot screws. These towers are wonderful.. so much easier to access the rolls!

Yes, I happened to have a box of metric cap screws that fit. Sorry for not being clear. I am pretty sure they are M6.

Thanks for sharing this! I'm printing the right-side tower as I type this. What size rod is this designed for? 1/4" (55mm)?

I assume this will work on a 2x as well?

As long as the mount holes for the back and side panels are in the same place then sure, I think it would. I do not have one of those, sorry...

How long does this take to print? Also what MB setting should I print on?

Took 4.5 hours for one side.

brackett27 on Apr 19, 2013 said:

It took a while (hours) but I am not certain, I am almost always running the printer while I do other stuff so I usually do not keep track. The settings I used are in the instructions.

The design needs knock out supports at the top for the grooves that hold the rod. I had to put my finger there to give the PLA something to land on. Still printing,,, I sure hope the Rep2 can bridge the gaps! I think it can....

jelos98 on May 19, 2013 said:

I... didn't do that. And I wound up with a 1/4" rod that fit VERY snugly after cleanup (note that it calls for a 3/8")

brackett27 on Apr 16, 2013 said:

There were a couple of threads when I did it, but they were of little consequence given my 5 shells. I snipped them out, they are under where the rod sits anyhow so you never see them. The more impressive bridge is the tops of the trusses which my rep 2 had no issues with. Perfect, no. Totally acceptable yes. :) I posted the SolidWorks files so if you want to add them go right ahead, I figure I will not be printing another set of these anytime soon. Of course you could just turn on supports in Makeware but I bet you would end up with a mess to clear and cleanup.

Nice design. Printing it now. You do know you can remove the "Do Not Lift" tag right?

brackett27 on Apr 16, 2013 said:

Yeah, I just never got around to it... I have a mattress and pillows with tags on them too... :)

I've been running my Rep1 like this for months. Not a single problem with snags or anything else. It's where the spools should be.
