3D model description

Cup holder in place of a front ashtray.

You can cut base model in your slicer in few pieces to print it by parts, like i did (see the pictures, there is a seam visible).

Compatible with the original cigar lighter and it glow bulb! Tested (see the pictures).

After print:
- sanding with ~120 grit (ok for further structure paint);
- use some flex putty if needed (in my case, with printing by slices and the seams between separatedly printed parts, - it was neccessary);
- structure paint for plastic.

Backlight between separated cup holes:
I recommend to use LED bulb for this backlight!
You can mold light guide tube with epoxy, with printed "_moldBottom" and "_moldTop" models. Or you can print transparent model "lightGuideTube" with some resin by SLA print.
Also there is "noBacklight" model attached, if you don't want to have this feature!

Adaptor for smaller bottles\cups:
Model also attached. Can be mounted in both holes, and don't need any glue or adhesive tape.
By default, inner diameter is 59mm. PM me if you want some different size.

3D printing settings

Optimal settings in my case:
Base model - 0.4 nozzle, 0.3 layer height.
Adaptor for smaller bottles\cups - 0.2 nozzle, 0.2 height
For the light guide tube mold models i recommend to use 0.2mm nozzle, and 0.1 layer height. Do wet sanding after print for better result!
