Brilliant design! Printed great on my Ender 3! Thanks much! :)

I printed this out for some AmazonBasics samples (http://amzn.com/B07D6DWT9Y) and it worked super well. It's the exact right size - any larger and they wouldn't fit, but as is the samples go onto the reel just barely, close up the reel, and cut the zip tie, ready to print. Thanks a ton!

Also, thanks for the tip on using the wire-wrapping stuff to manage samples. That's brilliant.

For loose filament spools ~90mm, I printed this at 64% and it works perfectly (I printed the spikes at 65% to make them easier to snap on). 1.75mm filament even fits the larger holes in the ends of the tines. Printed in PLA at .15 layer height.

Very fine design! Works great for my Laywood! Fits easily! Thank you!

Great desing, Thank you

If printer is well calibrated, pieces are easy to assemble

Printed well and fast on lowest setting. Pieces are difficult to get together, I needed to use vice grips to force them together.

Can someone tell me what the internal diameter of the filament spool is? I have some samples which are have an internal diameter of 90mm and am wondering if this will be too big to take them.

When assembled in the smallest configuration, the approximate diameter (I'm not being careful about measuring vs. the inconvenient five-way symmetry) is 140 mm, so you would have to wind your filament onto it rather than using the unlocking feature.

Thanks for the reply, I'll stick with the other (smaller) spool I've printed then.

Any chance you can update the info and include how many of each part need to be printed? I mean I think most people can figure it out but for simplicity sake it would be nice.

I'm still not sure how you put the unspooled filament onto this. Can you show us?

Im sure this is a problem on my end, however, the spurs do not fit on my printed forks. Everything was made to original scale. Would scaling up a bit to compensate help possibly?

Scaling is certainly the simplest workaround. But if you want to print other things, where individual parts need to fit together, I recommend to calibrate your printer and tune the slicer settings. Once done, it makes your life much easier. Here are some explanations:

I printed this out to make my Maker Box sample filaments easy to spool into my printer. I have had no luck getting the sample filament to spore properly on to this model.

What am I doing wrong?

Working great! Thank you!

Clever design! :) Thanks for sharing the files.
