Why are there no CAD files?
luzpaz opened this issue · 14 comments
I'm part of the FreeCAD community outreach team. There are a lot of volunteers on the forum that could be willing to help in this very cool endeavor. Feel free to post on our Forums to showcase your work or ask for help.
Examples:
- 3D printed canine hind limb
- Anyone interested in donating their time to make a clubfoot brace?
- Open Source Ecology onboards their community with FreeCAD
etc...
Thank you so much @luzpaz ! I'll look and post in the next day or two.
Our experience is such a testament to the need for FreeCAD, and why we base our work on FreeCAD and OpenSCAD as well. Thank you!
Here are the files not started:
- lens_holder_bottom
- outer_head
- lens_holder_top
In progress:
- battery_holder GlouGlou
- inner_head GlouGlou
- handle_coupler @eddriesen
- button_holder @0penBrain
- button_holder_bottom
@eddriesen@0penBrain - Lens jig Kisolre
Done:
I'm creating the files as we speak. Please do mind that freecad is new to me. So bare with me.
Things i'm figuring out atm.;
- part / body / project structure
- ok to use assembly2 module (prime time?/ Getting an error on 0.18.3)
- seperate proj file for each component vs project file with multiple parts or bodies vs seperate files and assembly2 project file
- any topdown / associativity possible?
Question; any possibility gaining the real source files (not meshed / with dims?)
No, Assembly2 is deprecated. Better to use Assembly2+ or Assembly3.
Please open a thread on the FreeCAD forums to discuss with the community. Thanks!
Thanks for the advice @luzpaz, and @eddriesen for your effort! I will open the thread tonight and post here.
I read you wanted help in converting to openscad (or freecad which I don't know).
I have started a bit, but it is much more difficult than expected. For example, The "button_block" looks as if it is the difference between three rectangular blocks (with critical parameters 18.45, 1.398, 12.747 and 13.000) and a sphere. But it turns out that sphere is not a sphere. So.... To help me: What kinds of shapes are involved in an object like the button_block ???
Hi @rewolff! Just a quick note that there seems to be an active effort to do this in FreeCAD at the moment, which I think is more fit for purpose. You are welcome to continue in OpenSCAD, but you may feel this work is duplicating the work of others.
Regarding your specific query, I have poked @Frankie-E4Rdesigns about this to answer you more specifically. I don't think your replica is obliged to be 1:1, though obviously the pieces will have to fit together in the end.
Thank you again!

Hi @rewolff
So the button block was made with two offset rectangles, and the "negative" of an elongated, rounded cone shape, the same shape used in the "button Top" piece, not a sphere as you suspected. The button block fits snug along the "button top", just where the rocker switch goes. I've linked a copy of all the parts used in TinkerCad for those that would like. The parts can be copied, and "taken apart" to see the different parts used and how they go together. I'm going to put the link here, it's good for 2 weeks starting the moment of posting this reply.
Hope that helps!

Specula Holder, Handle cover, button lock, neck part, button block, and handle coupler all look great!
OK, I figure instead I'm going to get rid of the PRs above and keep a list of TODO parts. This is a duplicate of the FreeCAD thread's list.. I'll keep it on the first post I made.
@tareko : regarding both lens holders, as it can be some critical parts, I think it is necessary that we can get a 3D model or mechanical drawing of the lens itself (or eventually some optical/mathematical description of it). May you provide that ?
Good idea on the lens schematics, will post something on that soon.
Different 3x magnification lenses will have slightly different dimensions, but I will post about the one I use.
