Raspberry Pi 2, 3 square round case (enclosure)

This is my rendering of a raspberry pi case for Pi 2&3.
The case has been designed for a NRF24L01 - MySensors gateway with MQTT.
The round hole on the back is to accommodate a threaded 5.5/2.1 female power jack. (like this one: http://www.fittcon.com/socket-connector-c-7/dc-power-jack-socket-threaded-female-connector-21mmx55mm-p-20.html)
The 2 3mm holes on the "front" of the case are for leds. My circuitry has a power led and a NRF24 radio activity indicator.

Update: after printing discovered a few issues (never design things at 2 AM, eh? :) )
- one of the case screw posts was slightly raised so the lid wasn't flush. (FIXED)
- the pi was sitting too low on the mounting pegs. (FIXED)
