My Solution For Spool Holder

After trying the Prusa Spool holders with little success I have design a more compact one that hangs the spools, fitting fairly tightly behind print on my work bench. The stand is working great. Though I might share. Let me know what you think.

Re: My Solution For Spool Holder

my complaint when using similar setups is the spools tend to run uneven because the weight is offset from the exact center of the spools.
I prefer to have the spools centered on some form of roller that keeps the weight centered.

the other issue is when changing a spool you will have to disturb the others which can lead to problems isolating them if possible is a better solution.

I've used the gear bearing to create some very nice spool rollers. they run just as nice as a metal bearing when you get them right.

Re: My Solution For Spool Holder

For anyone that built the lack enclosure, I have figured out an easy way to make things work with all the original bits:

1) print out some spacers to make the enclosing top table taller: https://www.thingiverse.com/thing:3016311
2) tape the five tubes to the top back of the enclosing top table so that they are sticking up a bit (you want to be able to get to them to insert the filament, and ideally you'll print some sort of proper holder, but tape works fine).
3) take the original spool holders for the lack enclosure and place them near the front of the table (or whatever you like I use this remix: https://www.thingiverse.com/thing:2972930 ). I also prefer the use of tape here to give them some anchorage. (But affix them how you like).
4) feed the roll into one of the tubes with the spool end positioned at the top of the roll (i.e. proper toilet paper position)
5) after feeding the filament, turn the spool counter clockwise 1.5 turns (it will now be in anti-toilet paper position).
6) after repeating 4 and 5, I lay a few rolls on the back end of the table to balance the table

Step 5 puts a small amount of tension in the plastic and this tension will take up the slack when the plastic is unloaded. By doing all the rolls the same, you will have several of these spring-like helixes along the top of your table. All of them will have the same chirality, and will not entangle with each other. Also it's important that your spoolholder be similar to the one posted above so that the bottom orientation of the filament will at worse scrape along the holder and the spool rim, rather than jump the spool.

If the steps above are not clear, I'd be happy to post a picture.
