My first 3D attempt - the Neckcheese NWP2 chassis :-)
Posted 02 July 2012 - 11:38 AM
Now it was time for something new:
So I made a new chassis in 3D and ordered it at an online rapid Prototyping company
I will receive the first prototype in 14 days, but you can follow the story on my new blog:

The material is very tough and seems perfect for this job. The surface is a bit rough, but not a problem in any way.
Holes are for 6mm bearings and the chassis is designed for the 18V 18D motors, like the Black Carrera and Plafit Bison. Basic measurements are the same as the original White Point chassis apart from the fixed WB and WP body mounts fits the chassis.
I moved the parts from one of my WP CanAm cars and all fitted perfect. With 23,5mm dia wheels the clearance is 1,5-2mm. It's designed for a low cut guide and has built in guide stops.
Also the body fitted perfectly:
The chassis is available from Shapeways: http://www.shapeways...r-wp-canam.html
Now for some intensive testing :-)

Looks promising - now I look forward to receive the 100mm wb chassis and the inserts for the variable wb's :-)

The front and rear is available as separate parts. There is two fronts - a "normal" one and one for very short nosed cars.
The parts have holes and slot and can be assembled with 2mm screws and nuts. Guide stop and motor wire holders are integrated in the design.
Wheelbase can be varied between 92-115mm without modification, but down to 80mm is possible with some shortening of the parts.
Recommended parts are 3mm axles/6mm bearings, 18D type motor (Black Carrera, Plafit Bison), low cut guide, min. 23,5mm wheel diam.
Guide stop - also shown behind is the holes for motor lead wires.
These are the 3 chassis currently available

Added weight in front of the chassis and two brass strips on the side grp wings

I use the rather simple software from www.emachineshop.com and export it in .stl format.
It has its limitations, but is ok for my limited brain capacity and the simplicity of the chassis design :-)

Is the Black Carrera motor the same size as the current carrera 1/24th motors?
Have you done anything yet on the 13D motor chassis?
Are your body mounting tabs threaded or is there a nut on the fasten to the top to hold them on the chassis?
Posted 21 September 2012 - 08:06 PM
If you choose the 1:24 motors, It looks so and from the specifications they are VERY close relatives and should fit in the chassis :-)
Even they are big and heavy, I like these motor as they are very very similar in performance and they can go for hour and hours. I have had motors that I used a full race season + a 10 hours race without any loss of performance.
Re the 13D, I havent got time yet, but the project is not forgotten, and hopefully next week, i'll have some time to do it.
The body mounts are made in 1,5 grp plate and i tread the holes. The grp is very dense and strong enought for this purpose. Another option is to drill a 4,5mm hole and press and glue the nut into the plate.
I have made some changes to the chassis to reduce material in order to reduce price as they are calculated per cm³ - i have received the test shots and i'm happy with them.
I also received 8 NWP2-962 chassis that will be used for club and rental car in our club. I am currently waiting for my delayed order for bodies from Truescale :-(

Reference your post above, Have the changes to chassis to reduce materials been made and in your shop? I am getting ready to order a couple of them and want the latest version. Also, am still extremely interested in the 13D version as (we tend to run 12v vs 20 over here) when it comes out. Will use the current adjustable chassis with big carrera motor to set up a Ferrari 458 using model kit to run against my other 1/24th carrera's.

the chassis on Shapeways are the latest weight/money saving versions :-)
- just drove one of them today in preparation for sundays' 4th and last round of the Danish CanAm Championship and it worked superbly :-)
The 13D chassis has been delayed due to multiple factors, but I will try to do something about it in a few days :-)

The body has been used for a similar race before, but are nice enough for one more outing :-)
Body: HowmetTX from John Dillworth AKA HowmetTX
Decals: home made
Silver: bare metal foil
Chassis: NWP2 3D-printed chassis from Shapeways with 18v Black carrera motor and foam tires

Latest version has some inprovements added - here is the first prototype print from Shapeways:
The latest version has body mounting wings integrated in the design - just cut off and use. Also the rear end has been strengthened with upper cross bar.
The mounting holes are now countersounk which allows the screw head to lay flush with the surface.
Add a little superglue to the hole, position the 2mm nut and press
