First of all. Thank you nracmo for the design! I have cleaned up a couple of parts, redesigned some of them to fit my need and raised the resolution. Further more i have designed a stand for the arm.

The arm is based on the second terminator movie.

Just follow the instructions and you can own a terminator arm lamp too.

Please note:
I have grouped the parts to make the print and assembly easier. If you need the parts seperated just use a tool like meshmixer or blender.

Choose the resolution depending on the parts. I have printed the big parts in a low resolution and the small parts (fingers, hand) in a high resolution to keep the details.


You need the following to build yourself a terminator arm lamp!

Nip off the heads from the nails. You need the heads for the fingers.

I have glued the parts with hotglue to some cardboard sheets to make the first primer round easier.

The process of priming and sanding was as following:

2 layers of primer
3 layers of primer
4 layers of primer
final sanding

I have tried to name the files acording to their groups.

The fingers were fixed with nails to the hand.stl. Nails were also used with the red pistons and the hand. As well as the turquoise colored small rods. The nails were also used to fix the red washers to the fingers and to close the holes.

After the parts where glued. The arm was spray painted with 2 layers of chrome spray paint.

The LEDs were installed in the base and fixed with some hot glue and zip tie.
The stand_*.stl parts where glued together afterwards.

Finaly the arm received a washing with black shoe cream.

Just mix some black shoe cream with water until it is very liquid. Apply it on the model and wait for a couple of minutes. After that take a tissue and rub the cream from the model. That way the black polish will stay in the cavitys and the arm receives more depth.

Just google "prop weathering wash" for tutorials.

The hardest part on the whole build is to clean the vase. Damn you fingerprints and smudges!!! :D

If you reached this point:

Congratulations fine sir or lady. You are a proud owner of a terminator arm lamp! Enjoy!

Great Job! I just recently printed the original file lol but I'll take these and modify to make the same thank you so much for the heads up on the glass tube I've been looking everywhere for the right size

The file is called index_and_ring_finger... :)

Thats right, but I see only one finger in the file... or i need to print it twice?

You need to print it twice.

are there any assembly instructions?

No. Where do you need help?

Not sure yet. I was wondering before printing. How easy it to put together once printed

finger_pinky stl is defekt???

No, the file is working fine.

finger_pinky is defect?

Super Idee, die gerade von mir umgesetzt wird.
Allerdings habe ich einige Probleme und einen Hinweis.

Zum einen habe ich festgestellt, dass die LEDs bei meiner Base durchleuchten.
Ich habe die Teile der Base mit "Fillamentum Vertigo Grey" gedruckt.
Wenn man nicht lackiert, sollte man besser mehr Außenwände drucken als die Standard 2 in Cura.

Große Probleme habe ich mit der Datei "hand_tubes" die ich nicht gedruckt bekomme.
Ich habe schon die 4'er Gruppen separiert mit Meshmixer, aber auch das sowie einzelnes drucken hat nicht zum Erfolg geführt (siehe Bild)
Jemand eine Idee, wie ich die letzten Teile gedruckt bekomme.
Ich habe es weder auf dem Ender-2 noch auf dem JGAurora A5 hinbekommen.
Das Problem ist, dass die dünnen und hohen Einzelteile irgendwann anfangen zu wackeln und in Bewegung geraten.

Versuch mal die Geschwindigkeit runter zu drehen auf 30%. Vielleicht hilft es, wenn länger gekühlt wird.
Ansonsten kannst du auch versuchen, eine Tube einzeln zu drucken. Dadurch wird er nicht zwischen mehreren Objekten fahren und diese zum Schwingen bringen sondern in einer Spiralenbewegung nach oben drucken.
Notfalls kannst du sie auch liegend drucken mit Support. Musst es halt am Ende nur ordentlich schleifen...

Germany is not far away from denmark. ;)
Or maybe ebay.

Sure, but I don't know what size LED it is.
Do you have any info or maby a ebay link ?

Looks great well done how long did it take to print and how much filament did it use?thanks

I did not write down the time. Depends on your settings and resolution. I belive it was under 1kg.

ya, so this is pretty freaking amazing! Thank you for sharing.

Thank you for the kind words dear sir!

what were your setting for the anycublc ? Supports mainly and on what parts

Just the stanard settings. Nothing special. Mainly on the parts with overhangs. :)
