Summary

Locks in the top of the Robo3D printer case, room for two spools. There is a logo version and a no logo version. Made it so my Robo uses less space.
Fits the Robo3D filament spools perfectly.
Update 1: Logo version cleaned up a bit.
Update 2: New version for spools with smaller spindle holes, minimum size 16mm. "spool holder logo 4 small.stl"
Update 3: Added longer spool holder, for those jumbo spools, by request.

Instructions

Looks good with a .2046 layer height,

is that trans blu?

Nope just regular blue.

have you tried trans blue?

is that trans blu?

So I printed one of these and used it for about 10 prints. It seemed fine during those prints. During one of the next prints it dropped the spool and destroyed the the print. A few days latter on the next print it fell off again but the build plate happed to be fully extended out the back. The spool fell so hard it shattered the build plate costing me extra money for no reason. I have seen better spool holders on thingiverse so id recommend one of those. This spool holder is very wobbly and needs multiple upgrades such as 2 cross bars. I am very disappointed and suggest no one uses this for their robo 3d.

I'm sorry to hear that. It works best with spools that have a little lip in the center. The new spools that are smooth don't work as well.
Again, sorry this broke your Robo.

Printed in matterslice, had to mess with the z offset but it went ok other than that.

It really needs tighter tolerances. They sit in the top hole really loose.

Also if you're printing with pretty much any filament that you didn't get from robo, you'll need to print out the "longer" ones. Normal spools won't fit on the short ones.

I built a part very similar to this and found that friction between the inside of the spool and the crossbar was causing tension to build on the filament and erratic feed. I simply wrapped the crossbar in teflon plumber's tape and now I have a very smooth feed.

After the first layer goes down it stops. on every model. This is the first design that has failed for me. Not sure what is causing it.

This has been up for quite a while, if there where any issues I'm sure I would have heard about it.
Try changing you slicer. If you are using matter control you have 3 options slic3r,matter slice, and cura. Try each one, they all have different strengths.

Any one else having a problem with printing this? After about 5 layers the 3 and the D areas gum up with PLA and crash on my nozzle. What am I doing wrong? The only way i was able to finish this was to turn on generate support material and then there isnt really a logo that is visible.

I have a robo 3d r1, e3d v6 (installed after having so much trouble with this print), PLA @ 185 degrees, bed at 60.

I have tried no heat on the bed as recommended by many people when using pla, after the 2nd layer the print pops off and is pushed all over the place.

Thank you in advance for any help you can give me.

You think that's bad, I have the beta ABS/PLA version. I could never get ABS to print right. Now that I've got the PLA going for me, I discovered that for some reason it goes completely off on the y axis for large builds (or multiple small items thus making it a larger build). I tried to build the other spool holder for space reasons but everything went bad. Luckily, this one fits because I can rotate it to build horizontally.

I realize this is a rather old post but I've had that exact problem on several prints of other parts, using both PLA and ABS. The root cause usually seems to be in either the z-axis being off, or the tension on the filament is too strong/weak. Even if you have the auto bed leveling version of the Robo3d the z-axis is the most common issue. Make sure the coupler nut is seated properly and fitting into the guide far enough that the limit switches don't slip off and spin on the threaded rod. That's what fixed my problem.

Tough to say the exact problem so I'll list a few,
-If the E3d is like the Robo3D hex it takes a bit more heat than before, I do PLA at 210 now. bed at 55 for the first layer than off after that.
-Print 2 at the same time so the layers harden up before getting printed on again.
-I use the purple aqua net and love it, blue tape actually works really well if you have some.
-last resort, make sure the print fan is on and slow down the print until the letters get covered.

Can you make the height of the spool holder another 1-1.5inches taller so it works with some of the bigger spools out there?

Allted - in reply to bob64

The new longer file has been posted. Hopefully this works for you. Let me know if it doesn't.

No problem. Could you give me a measurement from the outside edge to the upper edge of the spindle hole. Logo or no Logo? I guess I should do them both.

I have another spool holder that accommodates larger spools, that I haven't posted yet. It requires printing with support and I can't get my settings perfect for that yet. I'll put it up today, have a look at that one as well.
