Here is a 3D file for LPS Mini. Hope it will come in handy for those of you making your own plastic boxes/radomes. Keep in mind to avoid hygrophilic polymers! They absorb moisture and act as attenuators. Quick and dirty test: Put your polymer sample in a microwave oven and run it at full effect for a while. If your sample heats up it absorbs microwaves and can not be used. Another possibility is making a little plastic hat for the antenna and see if it affects the dBm-reading (P:).

This is how the 3D file looks in Fusion360:
