Job ID: 34642595

Budget: $10 – $30 USD

I need to finish design of a house for a cat that will be laser cut out of 1/8 inch plywood and assembled via interlocking system. I started designing it in Solidworks 2018. I need someone to help me finish it. You can use Fusion 360 as well but you'll need to redo the work that I've already done.
The house should have 2 floors and access doors to climb in for the cat
The 3d model needs to have either variables (equations ) name all features need to be clearly named, so the dimensions of the house can be changed quickly. Let say I would like to make smaller house , or use 1/2 inch plywood , it should take a few minutes to change the sizing. Please create a variable for laser kerf , so by changing one dimension I can change the fir of the joints. Uploading screenshot of existing design and reference design made out of cardboard , as well as sample interlocking system.
