Howdy,

A this thread seems somewhat static but thought I would say hello and get involved. I am pretty well versed in 3D and am currently in the process of fully 3D printing a pack. Up until this moment I have been running off Stefan's plans, but when I came in here looking for some missing info, it looks like those plans might be a little out of date and thought this project looked like on I could be a part of.

If I am going to take the time to model and print a pack, I may as well make it as accurate as I can. I will clone the repo and make a fork. I will have a look at modelling in Sketchup, but may stick to working in Houdini and outputting the STL files.

I am new to the pack building thing and am not that clued up yet on where the best reference is. Is there a primary source we are looking to work from, or are well pulling from multiple source?

Hope we can get this moving!

So I have had a pass at the synchronous generator. These are purely based of Stefan's plans. Does anyone know of any stats, measurements or references that would be of note here?

Built and added the cyclotron. At the moment this is all still in Houdini as it is much easier for me to make very quick and easy changes to any component. I will export the STLs at some point. I also want to go through and cut the object into parts that will fit into my print volume and make sure the parts are easily assembled down the line.

I have modelled all except the bumper. Top parts based on this thread, rest based on Stefan Otto's plans and changed the known factual errors, but still need better measurements :)

Nice work! Have you worked the bump into the geometry or is that coming from a texture?

I started on the bumper this morning and it is a pain in the ass in terms of shape. Everything else is just circles and boxes! I will send it to you if when I have it done if you are interested. Are you rocking in Maya?

If we got enough good reference photos we could smash the all through photogrammetry software and probably get something pretty good.

Thanks!

The bumpiness of the main pack is from the rendering texture. I figured it wouldn't help much when developing plans.

I'll put up a .stp file of my work so far if you want. I've hollowed it out to 3mm thick shell on most parts, the idea was to make it into flat pack files for scratch building one.... or just get proper measurements from =)

So... It's been almost three years since anyone has commented on this... How did the project finish? Is it finished?
Unfortunately it's been dead in the water for years. :(

I’ve been thinking of reviving this but using Fusion 360 (more geared to industry standards, better designed for this stuff), and breaking it up into components with one “pack” assembly.

That said: I was going to do that for an all-aluminum build so... might be constructed slightly differently in CAD form.

The main problem was being able to find a CAD program that enough people could use, was cheap / free and then for everyone to understand how to use the CAD and revision system on Github.

For example, I never really understood how to use Sketchup. I could have drawn the whole pack in Inventor (or Fusion360 though).

Fusion360 is free for personal use. With 3D printing getting more popular, it's getting a lot more traction in hobby adoption (and a ton of youtube videos & tutorials). I'd love to see a full CAD breakdown from the community.

Speaking of which, is there any interest in a dedicated 3D Print forum? I'd love to see more 3D printing incorporated. I was doing a search last week for thing to print, or to try my hand a designing some props of pieces given I've got nothing but time, but there's few threads on it.

I was thinking a lifeguard would be a simple fun project to model up and create a file, but I can't even find dimensions online.

Yeah, Fusion is great tbh. It's not only a good modeling tool it's a FANTASTIC CAD tool. However you do have to learn how to build CAD files *well* for it to be worth it (but it would be SO worth it).

re 3d printing - There's a bunch of Ghostbusters stuff on Thingiverse but I can't say how accurate it is. I figure a good, simple, first task for that would be the Walkie Talkies....
