I left a little slop in the top to allow your clamp some side to side movement.

The stand is tall enough for my bulky handle to rest underneath and still allow me to use it without picking it up.

Holds the clamps upright while you place the boards on top, allows for easier access underneath during glue up to clean drips or anything else you may need.

Still work in progress if there is any issues let me know. I have placed a fair amount of weight on them and don't suspect it will be an issue. If you feel you need to you can use more than 2 on a clamp. I would also suggest printing using petg and be mindful regardless in case these do break.
