Description
So, I ran across this design https://www.thingiverse.com/thing:3559087 and thought, "it is kind of a pain to swap solder spools out depending on what I'm doing." I had not seen the two-tiered Hakko 611-2 holder before. It's only about $18.00 on Amazon and, for Hakko anything, that's not bad.

That being said, why have a 3D printer if not for this vary reason. This is a far cry from a real clone of that priduct, but it works and I'm happy with it.
I print all my bench stuff in ABS but I think this should print the same in PLA. I also do 100% infill on everything, just because I want it to be sturdy and last. i'm sure a lower infill would be fine though. My first itteration was a bit big and it took 28 hours to print the base. I used the measurements off the Amazon link for the Hakko, but something is amiss there, or I'm just dense. They were 6.8 x 4.4 x 1.3 inches so that's roughly my original dimensions (minus the 1.3...not sure what that was). After I printed it, and saw how big it was, I ended up shaving 30mm off the front of it in the STL and just used a bandsaw to cut mine down by 30mm so you can see how it looks. I'll print another one at some point, but this was fine for now.
You can see the file list/explanations below, but i also added a base with holes to add the flux holders that led me to this idea (linked above). I did not notice until after I printed them, but the flux sirynge sits up a bit high in them. It would be better to mount them down lower on the base. You could also drill/file them out so the syringe sits all the way down at the T (this is what I did for the pictures). If you don't want the holes, or want to drill your own, you can use the base without holes STL.
For the guide that the solder spool feeds through, I just drilled holes after the fact. I can add the holes to the STL if there is a demand, but it would be super simple for someone to do in Tinkercade if they wanted. Make sure the hoes are far enough out of the way so you can remove the spool without having to remove the guide wire.
While putting this together, I had an idea to add a module to the back that you could hold different things with. I made one for tweezers, that's what's in the pictures. There is also an addonbase SLT that is just blank, and you can use Tinkercad to add any holes you want to it to store screw drivers, soldering tips, etc. This part is not needed though so you don't have to print it. It took me a little over 2 hours to print this one.
Printing:
For the spool holder you need a raft as there is little surface area in touch with the bed. If your printer is REALLY dialed, you may not, but better safe than sorry. They took me about 3 hours to print. I did support touching the bed only.When I printed these, I had not added the small cap at the top to hold the wick in place. Use your best judgment here if you think support is needed for the 1mm hang over at the top.
For the base, I just printed it on its back and it printed fine with no support but I did do a raft, just to be safe as it's a 20+ hour print. You may be fine without the raft though.
I also just printed the tweezer holder on its back with a brim. ABS has a tendancy to want to warp and the raft helps but your call. I did use supports for the tweezer holes.

For the Wireguide that the solder goes through, I used solid core 18gauge wire. This is what I used, but it's pretty standard 18 gauge:

Files:
Hakko_611-2_BaseV2 - This is the main unit that the spools rest in. This one does not have the holes for the flux add-on
Hakko_611-2_BaseWithHolesV2 - This is the base with the holes for the flux holders from the other designer
Hakko_611-2_SpoolV2 - This is the spool holder. It may still need some work. The post sticks out on one side far enough to add a small soldering wick (as seen in photos). After I printed this, I added a small cap on the end to hold the wick better. It only sticks out 1mm so I don't BELIEVE you need support there (support touching the bed only should be fine) but your miliage may vary.
Hakko_611-2_TweezersHolderV3 - This clips on the top/back of the base to hold the BangGood Tweezers I purchased
Hakko_611-2AddOn_BaseV2 - This is the file I used to create the Tweezers Holder. It's blank so you can import it to Tinkercad and add any holes/options/size you want. Things like small screw drivers, soldering tips etc.
