While I typically work in 1/35 scale items I sometimes do stuff in other scales. A client wanted a 1/24 scale Oxygen and Acetylene tank so I upscaled my 1/35 items on Shapeways: https://www.shapeways.com/product/SJWB49UAL/oxygen-cylinder-1-24?optionId=60830446&li=shop-inventory
https://www.shapeways.com/product/4PRAEQ8NA/acetylene-cylinder-1-24-scale?optionId=60815043
I also designed these as well:

Great idea. We need more quality scale items in this scale.

Can you make some front grille/head lights and rear end/tail lights parts for vehicle conversions in 1/24 - 1/25 scales?

I'd like to see front grille and head lights and rear bumper / tail lights parts for a 1974 Dodge Monaco. A little work and these conversion parts can be used to convert Rosco's 1978 patrol car.
