3D Printed DSLR Shoulder Rig new parts

For this Shoulder Rig
i have added some new parts.

Tube-Knob
A sort of Cap Nut
A new Rig support that you could stop the machine when you think it's correct for your rig

PS
I've used plastic tube, it's more cheap than Alloy!
Felts on the rig base.
Two sponge Knobs.

You need two 3mmx20mm screw with their nuts and two metal ring.

Remember that for this project you need 10 m6screw, 8m5 and patience!
