Best way to add Temporary 45's or PVC 1/2's into corners

I need to do some temporary testing in an SPL box and am wondering the best way to temporarily hold 45's made of MDF or so rounded PVC cut in half into the corners of my box to see if it helps my score?

I need to be able to put the corners in and then take them out if needed. Box is already made.

Caulk or duct tape

Screw them into place and use duct-tape on the edges to help smooth it out. You can always pull the screws and fill the holes with body filler or just some wood glue.
