Looks like someone has but they're selling them. If I could get the .stl of that I could graft it onto whatever tool.

I'll have a look later at this here dead 18V Ferrex multi tool I have. Won't take long to measure / CAD up for something that'll fit a Ferrex battery. It's just copying the base of the tool.

@ukracer, so you want to go from:
1) Ferrex battery to Stanley Fat Max Tool
2) Ferrex battery to Bosch tool
?
From measuring my dead Ferrex tool here I can I think repeat that so a Ferrex battery clips in.
I think my Bosch drill is the same battery style as yours so I have the tool/drill to measure from.
I'll do the Ferrex / Bosch first. You can print the trial bits!

@ukracer looking at the Bosch battery.....I assume your Bosch batteries are dead?
It'll be easiest I think to reuse the top off the Bosch battery. The top of the battery is held on by x4 T10 screws. One is hidden behind a plug you have to drill out. I'd look to retain the black battery top, also the red, sprung loaded catch that clips into the (Bosch) tool and the the pcb with the contacts on. Maybe too, the battery meter. Have the Ferrex batteries got a built in meter?

Yeah. Due to the fact I have 40 volt ferrex tools and batteries are 30 quid I thought it sensible to try and power any tools I can with those . I can then get a couple more and always have charged batteries that power all of them.

@ukracer I've emailed you the .STL for this. My take on the base of a Ferrex tool. For you to print out and see if a Ferrex battery fits. Note the Ferrex tools have 4 little rubber inserts in them. No ideas how to recreate them but I've included the T slots where they fit, on the model. We'll graft this to the bit that fits the Bosch or whatever tool later and figure the battery tabs/connectors too.

@ukracer me again! I've seen the Bosch battery shells for $10 upwards on sites like this:
https://m.aliexpress.com/wholesale/...annel=direct&keywords=Bosch+18v+battery+shell
But we don't want to do that!
Next I'll measure / CAD the Bosch shell.
No ideas as yet as to what to do to recreate the "forks" in the Bosch battery that fit on Bosch tool metal tangs/blades.

On to it.
Make them from phosphor bronze or brass strip.

Loads but not specifically Ferrex battery to A N Other that I can find. Ditto Yeggi. On Tinkercad theres a Makita battery to Ferrex adapter but that's the wrong way around.
Only thing I could find "Ferrex battery to whatever" was the paid for adapters aforementioned on eBay.

I've basically just done the same. @ukracer is the guinea pig!
Definately Pig. I have just demolished my home made Chinese Chicken Curry and on my 3rd Bourbon and Coke whilst printing some new filament holders as the 3DQ cardboard reels have a large center hole. lol
Strange thing is he is using connectors but claims its just to screw under a bench to holder the battery! He does not claim its an adapter..

He's worried about liability should the adapter be used with another make and a fire etc result from it. Let's face it, using these adapters will go against the manufacturer's instructions etc. We all know that...does it stop us?
Interesting finish on the battery tabs he seems to have like they're plated. Conversely you can see the saw/machine mark's on the edge.
Clearly designed as a breakout box for other uses. 1/4" spade take off by the look of it.

Thanks. Tbh I'll probably copy what's on the Makita to Einhell adapter. Seems to work well. 1mm copper in two pieces. So it'd be something like this to connect into the Ferrex battery "females" but 4 "blades" instead of 2:
Then something like this, a formed spring clip to go onto the Bosch tool blades in the underside of the tool:
I have a plan...sort of...

Apologies but my lad still hasn't gone onto FB yet and engaged anyone over this ABS printing. He has a major aversion to FB as I do tbh. Not overly sociable either...wonder where he gets that from?
He's been working on Python code to fit multiple temperature sensors in the printer cabinet. He gets stuck and has a wobble, I offer to ask in one of the many online nerd herds I frequent. He says to hang on. Next thing he's figured it even if it's taken him all night. All we can do is offer to help and try and steer them!
It's getting that I might have to sign up to FB myself!
