Optics Mounting Case

Little optomechanics box I designed for a laser source in our lab. Rings inside are designed to allow for appropriate bend radius of fibre. Hole on side is to allow a power cable through, or just something that isn't fibre. Slots on the side are to friction fit FC/APC fibre optic mating sleeves like the one attached https://www.afwoptics.com.au/index.php?route=product/product&path=82&product_id=403. Let me know if there is anything you'd like changed.
