'ROCKETZ'... Interlocking Storage Stages and Fun Model by muzz64 May 21, 2016


'ROCKETZ' are a 5 part interlocking model of a cartoon style rocket. The lower four stages are storage compartments and the top / capsule is functions as the cap for the stage below it. Refer to the images for additional information.

The largest storage capacity stage is at the base (engines) and each of the stage further up the 'ROCKETZ' reduces in capacity. The total height of 'ROCKETZ' is 235mm with all stages fitted. Be creative by printing 'ROCKETZ' in your color/s of choice... or print different stages in different colors.

Each stage lock together by aligning the lugs with the opposing parts slots, pushing the parts together then rotating 120 degrees to lock in place. This means you can carry your 'ROCKETZ' around and they won't fall apart. It also means you can access a single stage to add / remove things without opening the other stages.

'ROCKETZ' will take time to print but they are well worth the time and plastic... the result is a unique model that can be used to store away all sorts of small things from Lego / toys to nuts / bolts / screws, electronic parts / components and any other small things you need to store away.

The stages are all easy prints. No support is required. Raft is recommended for the engines and capsule in particular due to having less contact area with the build plate than stages 1 / 2 / 3.

The joint clearances have been intentionally left slightly loose to ensure most machines should be able to print this well with no issues and interlock correctly for use. If you want to uniformly scale it down 10% should be okay but any more is likely to reduce the clearances too much so the stages won't interlock.

Please refer to the print settings and images for additional information.... and post your pictures of the 'ROCKETZ' you make being put to good use.

Print Settings

Printer Brand:



MakerBot Replicator (5th Generation)






Standard / 0.20mm


2 shells / 15% or more infill recommended


Easy prints in PLA... to print all 5 stages takes time but the result is worth it. This is a unique fun model and practical storage system in one.


Just assemble / lock the parts together...

Assembly is easy... just insert the upper stages into the lugs of the stage below it and turn 120 degrees to lock in place.

Please note: Stage 2 will lock into the Engines stage but will not look correct or be a correct fit.

Thanks for the awesome design!

This is a lovely rocket model, I've printed up three w/ various colors in PLA, I'm not savvy in the design aspect of these things so I was wondering if any remixes of this fab start were possibly in the future, like different fins, or capsule shapes, port holes, more stages to stack etc.??? I know I would print many for various kids in our church small group

what could go wrong if I scale this down to 40%? What should I change?

As you scale it down the designed in clearances will also reduce as well as the wall thickness and parts that lock it together. The result of scaling down too much will be a fragile print and it won't fit together.

If you have a well set up machine that prints fine detail well you may get away with 20% but 40% is likely to be too much.

I hope this helps

For some reason, mine isn't locking. I havent scaled up or down. any ideas?

This design shouldn't need any supports when printing in PLA on a machine with an effective filament cooling fan (which most have). ABS is likely to be a different story as it won't deal with the angles and overhangs as well.

I'm obviously not sure where you are having issues but it could also be with your machines ability to bridge. The fact is all machines and slicing apps are different. The images on the this site are of rocketz printed with no supports and plenty of members have had similar results. Unfortunately this really does come down to working through what the local issue is... is it the slicing software, machine or filament (i.e. ABS?)

I hope this helps but really can't suggest anything else because they print great for most people...

In the Thing Details it says not supports are needed put mine needs supports no matter what I do

Did anyone try to scale it up?

Will there be problems with the clearances at lets say 200%?

Scaling it up uniformly should be okay but the clearances will increase proportionally... as a suggestion print the two smallest parts at the required scale to check you're happy with it.

Just finished the bottom 2 stages at 100% and the gap is a bit loose, but 3 dabs of bondic on the holding tabs fixed that.
nice model!

Maybe I'll try one at 150% sometime, but with 2 kids, I first need to print 2 normal ones, don't want to get into trouble. :)

Pleased you have worked out a good solution... and kept your kids happy!

Lovely! I'm going to print this for my kids! Thanks

I like how you you sent my things to the moon without my permission on the 6th image
