Videoton pong battery door

Battery door replacement for Videoton TV Foci.  I simplified the original design a bit:

• I did not include the ridge that it had in the outer side of the original

• I skipped the rib that strengthens the back side (I suspect that was mainly there for injection molding)

• I used M3 heatset insert instead of M4, since that's what I have at home (and probably everyone involved in 3d printing)

I also made 2 modification after the final print that I pictured:

• I widened the top of the grades to make it easier to print

• I decreased the diameter for the heatset insert

Designed in onshape. Print it upside down, with supports under the tabs only. You'll need a 5x5 M3 heatset insert for the screw.
