I got my son an Airsoft gun for Christmas. He wants to start playing with his friends in a league. One stipulation I had is he needed to keep it up out of easy reach of smaller kids (plus he must keep it without batteries installed and not loaded).

So we sat down in Onshape and designed a wall mount that allowed him to mount it above his closet door out of the reach of younger kids. Plus my son is over 6ft, so he can reach it while even I struggle :).

This is specifically for the Matrix "Calico Jack" Polymer M4 Airsoft AEG Rifle w/ M-LOK Handguard & MOSFET (Model: PDW / Tanker Stock / Tan). AKA Double Eagle M904. I got it for him on EVIKE.com = ID: 20710 (AEG-MTX-M904N-E1-TAN)

Here is the Onshape link to the CAD if you want to modify it for your own uses: https://cad.onshape.com/documents/f6fe061e7b6c09ee035f1d4d/w/ca6ca0606f50a51a9347a0be/e/201e481fb654b2f3a29d95ec?renderMode=0&uiState=658b60ca31f21b24b3c7fce4

I have included the plated STL's and a STEP export if you want to modify it in your own CAD software.
