This Raspberry Pi mount allows you to mount you pi to the side or top of your frame. Should work with 2.5mm screws. Will post pictures once I've mounted.

It is a remix of the Michael's design but adjusted so that there is room between where the item is mounted and your raspberry pi. (Good for accessing gpios easier)
