Collars are super cheap. I would totally buy those.

Oh, you mean the beam couplers. Sorry.
You can make a straight coupler, but it'd be a lot of work to get a helical beam coupler made in shop.
There are knock off brand ones on ebay and amazon for cheaper. A lot of diy CNC suppliers stock them as well.
They're not real commonly used in FRC, the size and weight are somewhat prohibitive.
