Peter.collins443 Posted June 5, 2018 Share Posted June 5, 2018 Last year I purchased a Corgi Classics Twin Axle Flatbed Trailer Model 1 50 Scale Ive been looking for some one to do some 3d printing. I noticed a London fire service foam unit on flickr and I decided to not create the foam unit itself but the High expansion foam containers and a few other pieces. But to date I have not found anyone just willing to create the items I want. They normally want to create the full item.. Maybe at a later date. So do you know anyone that can help Ive attached images of the unit I purchased and a few pics of the foam units to give you an idea of what i'm after.

rue_d_etropal Posted June 5, 2018 Share Posted June 5, 2018 My starting point is always scale drawings. If someone can provide those(assuming I don't already have them), then it is relatively easy to do a design for 3D printing. I then use Shapeways to do the printing, so I could be thought of the link between the documentation and the manufacturer, but I can't get involved in either of those.

Peter.collins443 Posted June 13, 2018 Author Share Posted June 13, 2018 Ive had time to search for a Bulk foam container that is used by the fire service. the size of units are Height (mm): 1160 Length (mm): 1200 Width (mm): 1000 So how do i find out the relative scale. The model is 1:50 Peter Collins Link to post Share on other sites More sharing options...
mikeharvey22 Posted June 14, 2018 Share Posted June 14, 2018 (edited) I would 3D draw it at 1:1 scale then reduce the size to 1/50. To get the 1/50 scale size just divide each dimension by 50, so:- Height 1160/50 = 23.2mm Length 1200/50 = 24.0mm Width 1000/50 = 20.0mm Edited June 14, 2018 by mikeharvey22 Link to post Share on other sites More sharing options...

So in reality I'm looking for about 12 individual bulk foam containers for the trailer and this leaves me space to get a couple of other things to be made.

It was printed on Anycubic Photon printer. It uses a liquid resin and solidifies with UV light. In some areas it has very slight stepping, but after spraying most of imperfections are not noticeable anymore. Like the small stepping near the top cap. Below is the photo of painted tank.

It's pretty much the current standard for describing 3D models. Exactly. It does not matter what software you use as long as it allows to export to STL format. But I prefer more engineering software than Blender where I can set all dimensions very precisely which is sometimes crucial to get a correct print. Especially when we are talking about prints which are close to the printer limits. For example this one was very tricky to print: Vertical bars are 0.5mm in diameter. 4 Link to post Share on other sites More sharing options...

Takes a bit of effort to get the hang of it, but it makes producing something like this quite simple. Four Britannia chimneys 1/76.2 scale. 1 Link to post Share on other sites More sharing options...
brian777999 Posted June 27, 2018 Share Posted June 27, 2018 (edited) Andy : could you elaborate a bit more on why you think Turbocad Pro is better than Blender ? I am in the process of evaluating 3D software with a view to buying a 3D printer...probably the Anycubic i3 Mega. NOTE : It would appear that Turbocad Pro is free : is this correct ?

I am in the process of evaluating 3D software with a view to buying a 3D printer. Hi Brian, I'm no expert on Blender (I've been using various versions of TurboCAD for 25 years) but from what I can tell Blender is more focused on the creation of "artistic" (for want of a better word) models than engineering models. It's quite simple to convert 2D drawings into 3D models in TurboCAD. I'll run you thought the basic steps of producing one of those chimneys: Ignoring the bottom flange, draw an outline of the profile of the chimney to scale in 2D. Select the 2D profile and "Revolve" it around an axis to create a 3D model. (We're about half-way there) To make the flange extrude a 2D circle that's the diameter of the smokebox to produce a cylinder. Extrude another circle into a cylinder that's slightly larger on the same axis. Subtract the smaller cylinder from the larger cylinder to produce a tube (that's the flange, but it needs to be trimmed). Logical "Add" the tube with the rest of the chimney. Draw a 2D circle that's the diameter of the flange (in plan) on the axis of the chimney. Extrude it into a long cylinder. Logical "3D Intersect" that cylinder with the other bits that were previously added. Now 'Modify 3D objects' - "Fillet Edges" to merge the flange into the rest of the chimney. Last step is to "drill" the hole in the middle with a logical subtract. Yer done! (I've left out a few details but I hope you get the general idea.) If you wanted it to be a double chimney you could slice it down the middle, "Pull" the exposed faces by a specified amount and "Add" all the bits together to create the model. Now I'm not saying there's anything wrong with Blender and you could probably make this using Blender too. You'd have to try something like this to find out how it would go. A lot of this could also be done in the less expensive TurboCAD Deluxe, but it's not free either. I think the worst bit about any 3D modelling is knowing which 2D plane you are currently operating on. I don't think that's going to change much Best, Andy Link to post Share on other sites More sharing options...
AndyID Posted June 27, 2018 Share Posted June 27, 2018 Brian, Alas, TurboCAD Pro is not free. It's quite expensive. TurboCAD Deluxe is less expensive, but not free either. You might find a back-dated version of Deluxe or Pro for sale that's not too expensive. I'm running the 2015 Pro version. I had a look at the various freeware CAD programs I could find recently and I couldn't find any that met my particular needs. I suppose it's an example of "you pays your money and you gets what you pays for". Andy Link to post Share on other sites More sharing options...

Spitfire2865 Posted June 27, 2018 Share Posted June 27, 2018 If you want to do non-commercial work, try AutoDesk's Fusion 360. Get the free trial, then in the top there is a "license" option. If you confirm you wont do any commercial work, you can get it for free. Link to post Share on other sites More sharing options...
