C51 4-Bit Clock Kit Enclosure

I've ordered a solder kit from Amazon. The kit is C51 4 bit clock (https://www.amazon.it/Kit-elettronico-orologio-Production-Suite/dp/B00Q6Z3KYG/ref=as_li_ss_tl?ie=UTF8&qid=1486315136&sr=8-1&keywords=c51+kit&linkCode=sl1&tag=0labit-21&linkId=c82d1ee8ef559f71b652e1a186082d01). This kit haven't an enclosure. Also the clock haven't memory because there isn't a battery inside for memory. I've designed an enclosure that have a slot for 2 aaa battery, only for leave the setting in memory. Also the enclosure have a hole for USB cable. I leave opened the enclosure because the beautiful of this clock is the electronic board, and the components inside.
