Jasper Table Rail for cup holder

I purchased a Jasper Table on kickstarter from https://www.boardgametables.com/.
The table came with rails to connect cup holders only on the short end, not the long end.
So I printed extra rails. I figured out that I can use the rails on other tables too. So now I have cup holders everywhere. The rails are 200 mm in length.

I used #8x3/4" flat head Phillips screws (3/rail, 12 total for 4 rails). I suggest predrilling the holes. It can support the snack table too. You will need to make a jig with the cup holder to position the rail before you screw it in. My Jasper table is dark colored so I laid down blue tape and made markings on the tape, predrilled one hole, removed the tape, screwed the rail in, then drilled the other two holes and screwed in the remaining screws.
