To save some space I wanted to stack my Hakko FX-888D soldering iron on top of the station and when I saw the soldering model event I though now is the time :)

For a simple version you can use the top and bottom pieces for a place to stack your solder iron holder. 

The more deluxe version includes a magnetic drawer for a place to hold your tin and soldering tips a (8 x 6.5mm holes and 3 x 7.5 mm holes, note the spacing between tips is small so you'll probably want to keep some spots open)

The drawer includes two mounting holes which turn the drawer into a helping hand.

Although I haven't used it much I think the dupont pin jig might be quite handy.

Hardware needed:

Top mount only:

• 2 M2 threaded inserts, length 2.7mm
• 2 M2 15mm bolts

(I did some dirty photo editing since the picture I took contained the M2 8mm bolts, the top mount needs longer ones..)

Drawer version:

• 6 M2 threaded inserts, length 2.7mm
• 6 M2 8mm bolts (the 15mm bolts are not needed for this version)
• 2 12x3mm round magnets

No glue needed :)

The parts without ‘needs supports’ in the file name can be printed without supports.

I used PLA for the station parts and PETG for the helping hands, note that tolerances on my roll of PLA is quite bad and I have adjusted the thread sizes for this. With better filament it might be a bit loose. (The filament does have a nice colour changing effect to make up for it, so there's that :)

Version updates:

5 Feb 2024: increased the size and width of the lines on the solder helper nuts and bolts. (v1.3 versions and 2.2 of the pole)

18 Feb 2024: When designing models in sketchup I scale everything to reduce rounding errors, i forgot to scale the drawer back to reality :) The scale of ‘Hakko Stacko - FX888d - drawer - v1.2.stl’ should now be correct, other then the scale the file is identical to v1.1

Construction:

Top mount:

Only the base needs threaded inserts:

(Here you can see the color change in action :) at around 30 degree Celsius it turns yellow)

Drawer version:

Start with the threaded inserts, base:

Top:

Middle:

Add magnet to middle part and drawer, check that you use the right orientation before adding them otherwise you get an automatic ejector drawer ;)

Screw the middle part to the bottom:

Repeat on each side

Note that the battery lid has a slanted top so it stays in place, check orientation if it does not fit.

Repeat on each side

Done :)

For a good set of helping hands print: (but to be honest the helping hands are not terribly good..)

• 2 arms
• 2 cap nuts
• 2 caps 12mm
• 2 caps 15mm
• 1 dupont jig

The 18mm caps where a bit hard to screw in all the way with my prints, but you might find them useful if your printer/filament has different tolerances.

The spacer might be useful to you depending on your configuration to level the mounting points.

Note the ring on the middle part I intended as a place to store a cold iron to make the cable stick out less when not in use, but I am sure sooner or later I will turn on the iron while forgetting to move the iron.. It can still be used for the cable plug though. If you use the ring for the iron use at you own risk..

Enjoy and happy printing/soldering :)
