Created because I needed a good reference model for another toy crossover design. I started with TheNewHobbyist's model but redrew it from scratch using other downloaded images. I sliced up the handle into different pieces for each color so it can be show-accurate without painting. Also added a tip and core piece, fixed it so it has four prongs instead of six. Finally the telescoping part and opening prongs should actually work now. The printed model won't be spring-loaded like the actual toys and props are, so you'll have to extend it and open the prongs by hand, but the detent to hold the telescoping section retracted and the prongs in should work.

I have printed this now. Seems to print OK although there are some tricky overhangs. The core and tip should have been done in translucent green, but translucent blue was all I had on hand.

Note: minor change made to white_handle to add hexagonal indentation. Also, uploaded the source file.

Updated with hollow version, for use of those of you who intend to put LEDs or remote controls or other devices inside. The handle is also connected to the cage with a twist to release mechanism for replacing batteries. This is the version printed above, which seems to go together well but I haven't tried actually putting anything in it yet.

I have also added a version of the black part of the handle that is hollow and has a slot specifically sized for an Arduino Pro Mini.

As a warning - this model is fairly fragile. The tabs between the white and black parts of the handle don't work very well, are quite fragile and don't lock securely so I recommend just gluing those parts together. The sliding parts on the cage are also fairly fragile and are likely to break if you open and close it too many times. If you intend to use this as a frequently used toy or prop you are probably better off just gluing the movable parts in the open or closed position.


Print out one each of the parts, except for the 'silver_prong' part which you need to print four of. The color of each part is indicated, except for the 'connecting_rod' part which is buried inside and not visible so it can be any color.

The 'green_tip' and 'silver_cage' parts may be difficult to print without support, so I have included alternate versions of them that have manually added support attached.

The connecting rod goes inside the parts 'gold-end', 'white_handle', 'gold_ring', 'black_handle', and 'green_core' and holds them together. Press 'gold_cage' over the outside of 'green_core', and optionally glue all those parts together if they aren't rigid enough without glue.

The hollow version does not need the connecting rod, instead fitting together with tabs on the insides of each piece.

Cut four 10mm long pieces of 1.75mm filament and use them to pin the four 'silver_prong' parts into the 'silver_cage' part. You should then be able to snap the silver cage over the gold cage. Press the green tip piece into the center of the silver cage, use glue to attach it to the silver cage if required. The green tip should telescope in and out of the green core when the silver cage is moved forward and back.

I haven't yet printed this model, but everything should ft together. I may be updating these plans and instructions once I have printed it.

Just to point it out: since this seems like a scan of the CO toy, there are slight inaccuracies. This is still awesome, don't get me wrong, I'm just a sucker for screen accuracy

This was drawn basically by eyeballing stills from the show - I didn't have access to any of the toys or props to scan them. It's probably not terribly screen accurate, just as close as I could get it by hand.

Great design! i printed it for a costume. would you ming however sharing the design files?

whats the intended nozzle size?
im having a few problems with a .4mm nozzle

It is actually good that it isn't spring loaded because the prop in the show it isn't.

yeah, its a flick and lock

Can anybody tell me how the green core hollow attaches to the golden cage?

i wish i could make it and have it

On the hollow version of this, on the white handle . . . It appears to be impossible to get a print of this in either ABS or PLA that will actually snap together without breaking the fingers off the white part . . . they are just plain too small and flimsy! The rest printed and assembled fine, and I am making a variant of this part without the locking tabs, so that it will maintain alignment while being glued in place.

A small amount of rework to make the base of these thicker, and this will be gold . . .

lol, cool model... it looks like even an old, out of date printer could print it... 10/10 on printable-ness and cool factor.

Comments deleted.

Does anyone know how much this Sonic screwdriver weighs? Specifically in grams but any measurement would help. Thanks.

That depends on your material, infill density and wall size.

That is so cool and the really cool thing is that it move

I printed it on a Printrbot Simple, and it came out just like the one on the picture above, except the blue part was painted green

Made one. Amazing ! thanks :D

I'm still trying to figure out which make looks the best.

Having trouble printing the silver cage, with and without supports.

Suggestions, anyone?


I was just watching some videos on youtube and before i noticed i had stuck my pinky in that part and could not get it out anymore :')

Had to break it carefully to get my pinky back :P

Kinda stupid but hopefully it saves someone else ;)

Obligatory: "instructions unclear, pinky stuck in fan"

The White handle hollow twist... is not. It has the tabs which, by the way, snap right off.

The tabs on the white handle snap through the gold ring and into the black handle part. That is the same on the twist and non-twist versions. The twist part is the gold end piece, which inserts into the white handle and twists into place. This all works on the one I printed on my machine.

Has anyone made this yet? If so, please post.

I cant seem to get gold_end_hallow to come out right the conector pices snap to easly and they move while printing causing them to not finish.
tried doing it sideways w/support (total fail) ruins the sids and only a few of the cnecting pices/snaps came out even in that orentation and there week.

any sugestions?

I made a modified version of the gold end piece and the white handle piece which has a twist-to-connect mechanism instead of snap tabs. That seems to work a lot better and print more consistently, and it allows the end of the handle to come off if you're planning to put batteries inside. I just uploaded those files now.

Love it! I'll be making this soon!

If you don't want to go out and buy all that filament for the colors you don't have, one option is to print it clear or white and color it with model paint. I think this will work for most print qualities.

Also, would you please add your design files? Maybe someone can adjust the design to include a ball point pen spring for spring loaded action goodness!

Ok. Uploaded the autocad source file.

Awesome! Downloaded again!!!
