Yea you can build one easy enough
People's stuff always comes out crappy in woodshop because they either
1)Don't care
2)Don't try
3)Are handicapped
4)All of the above
If you take your time and care about trying to get it perfect then it'll come out nice
Hardest part is getting access to the tools like table saw, router, drills, miter saw. You could improvise but its much easier if you have all the tools already
