You move up to parametric modeling. Here's the model I made of my Festool SYS1 T-LOC systainer, accurate down to ~1mm.

I undertook this effort as a training exercise to learn CAD/CAM. It was quite challenging due to some of the very complicated contours used in the handle and latch, and some shelling issues I had with the main enclosure. I certainly didn't make it the best, or most efficient way, but I'm pretty happy with the outcome.

It also gave me a new-found appreciation for the amount of engineering that went into the construction of these "plastic boxes." The attention to detail is very German. 

Now, it won't take much time at all to model the other sizes of systainers, since they all share the same footprint (just different enclosure heights and some small modifications to the housing.
 
Hi Ryan,

That is an amazing "apprentice piece" and quite a challenge no doubt. I suspect the only problem that most FOGgers will encounter is the price of Solidworks which is way beyond my budget. I just stick to 2D work using Draftsight which is completely free and has no adds built in - another great program from Solidworks.

Would the files that you have created allow you (or someone) to produce the design of the moulding needed to produce the systainer?

How long would you estimate the average person would need in order to get to your level of expertise with Solidworks 3D?

Many thanks and again, a brilliant piece of work.

Nice job...really well done. The level of detail that you've included is impressive.  [thumbs up]

After an exercise like this, you really have a better appreciation for the amount of work that's needed to properly injection mold any plastic item.

Just curious if Solidworks is capable of turning the final part design (what you have), into the injection mold cavity/force design by compensating for material shrink factors and adding the proper draft angles and fillets?
 
Ryan, that is Awesome work!

Peter, agree on the cost of high end design tools  We now have access to Fusion 360 which is free to makers and hobbiests under Autodesk license.  It will import Solidworks files and has many of the capabilities.  Rendering is excellent.  Maybe a notch below Solidworks but very capable.

Check it out for a really well done cad, cam, design, and rendering program.  Mac, Windows design capabilities.  View, markup and share on iOS or Android.

Thanks for sharing.  How many hours in the model?!

I think SolidWorks has an entire suite of tools dedicated to mold-making, which I haven't gotten into at all. That's mechanical engineer territory, and my interest here was mainly to model it as close as possible. I'm not quite sure if it could be used to make an actual mold, but it would be fun to test out.
 
How long did it take to learn this skill? I've been using CAD as just another layout tool for 20 years and I'm still a novice, nowhere near able to do what you've done. I never sat down and committed to serious study.
 
very nice! in some angles the latch looks better than real life.
 
A very useful module of Solidworks is 'EDrawings'. A solidworks model can be sent to anyone along with a viewer that will enable them to open the model without actually having a Solidworks program or license. I can view models on my iPhone with EDrawings, rotate, section views, select components and even measure features with the built in tools that come with the app. All manner of CAD tools are built in. It is totally free and very powerful and robust. It would be a great sales tool to be able to give a solid rendering of a pice of furniture or even an entire kitchen to a prospective customer. It can be even be annotated and sent back to the originator.
 
You have WAY TOO MUCH time on your hands  [big grin] [big grin] [big grin].....but excellent work.

If you haven't done so already, learn about "Configurations" and controlling dimensions for each one. This will allow you to model all of the systainer sizes within a single file/assembly.

Yes, SolidWorks will directly convert this into mold shapes, but it is frequently best to just let the plastic fabrication company make that conversion based on their specific capabilities. They will take the raw SolidWorks files and tailor them for their needs.

If you want to share your assembly with others, there is a website, GrabCAD for sharing models. You can upload the native SW files, but I recommend that you also upload a "Parasolid" export (.x_b OR .x_t) for people like myself that refuse to upgrade to the newest version of SolidWorks. (Parasolid is the best format for SW-to-SW transfer between versions.) I love SolidWorks, but I despise the business practices of the company.

Oh, I just looked. Someone has already done a systainer on GrabCAD, but nowhere near the detail you have done. It was just a poor shape-size model.
 
P.S. As a long time SW user, when I look at some of those features, all I can think of is how tough some of them were to put in. As a new "learner" you definitely have my respect!
 
Yes it does. Solid works has gold partners that plug in for CNc cam, mold, electrical, pipe and wire, photo generation, etc. use them on a daily basis. Easily the most user friendly cad program on the market.

So [member=45856]blaszcsj[/member] if I understand this correctly, you construct the piece part drawing as to how you want to see the finished item, and then you introduce the plug-ins depending upon how you want it to be produced, i.e. CNC'd or injection molded.?
 
[member=44099]Cheese[/member] the third party plug ins essentially expands the basic cad package and allows the various disciplines to operate off the same cad model. In regards to specific manufacturing method, the CNC CAM add ins would Allow the user to port in a CAM package for tool patching and automatically post process for the specific machine.

As far as mold making, the basic cad package would allow you to design the mold. Once you have the part, you can do a simple Boolean operation (generate the negative), add draft, and split it where you want parting lines. The mold plug in is really for mold flow analysis to optimize flow for production operation. This app is usually used by mold design companies and not your average user. The CNC CAM packages are probably the largest purchase of third party plugins for solid works.

The photo suite is built in I believe and some of the higher analysis functions depending on the package level purchased.

Gotcha..thanks for the info....I'm familiar with Moldflow and used it when it was still an Australian owned company, before they were acquired by Autodesk. They were the first to produce software for mold flow analysis.
 
Finished the SYS5 based on the SYS1 - there were actually quite a few distinctions here and it took me more work than I expected. The front feet are different, there's additional ribs on the inside of the enclosure, and SYS2 through SYS5 include the support bracket from the factory (which is a huge PITA to remove, by the way... almost broke the case to get it out).

Going to work on SYS2 through SYS4 next (they'll be very quick), and then move onto SYS-AZ drawers. My ultimate goal is to have a fully-functioning custom SYSPORT. I'll have spent more time modeling than woodworking.  [blink]

Well, the bad news is that is the old support bracket, there is a new one so you'll have to update your models. [tongue]
Check out this thread in the dealers section here on the FOG, UK - New strengthening bar in Systainers?
 
As one who has been relying on SolidWorks for our designs, including the both GRS-16 Guide Rail Squares,  agree that modeling the SYSTAINERS as a reverse engineering exercise is quite impressive - very well done! Since this thread is into the design of our tools this is probably the right opportunity to point out the enormous complexity not to mention the complexity and huge cost of the injection molds. The industrial designers were turned loose with a serious commitment of capital to see the product development through. And then came the replacement of the design with the TL version.

After the tools are done  and function as intended, there is then more than the average level of manufacturing skill required to mold parts with walls this thin which are expected too mate with the lids

The tooling complexity/cost also explains to me why it has not been duplicated here in the US. More economical to suffer the shipping and logistic expense of exporting from Germany.

For anyone interested in non-commercial use of a serious CAD software package:
SolidWorks is available as a free MAKE version including some finite element analysis. If there is interest by the FOG I will post details for US access to the free version.

Yes, please do.
 
Nice work. It's been many, many years since I've done anything in 3DS MAX or similar software. I can't say that I ever got to the point where I had any level of expertise. I worked with guys who used Solidworks and other software who had some pretty serious skills. Your models are spot on and well done, congrats.
