Hello,
I created this design to not only securely hold the model kit, but also display the kit in a unique way. I wanted something that would allow me to have a range of motion to be able to give the model kit more options on how to pose as if it were in space.
M3 top screws are more cosmetic, best way to actually tighten them is with a 2.5mm hex key.
What I've tested, when the arm is fully extended it can carry 1/2lb easy, depending on how much the screws are tightened. I haven't tried putting a mastergrade on it yet, but if someone does and it works, that would be awesome!
For the M3 nuts the best way to put them is by using pliers and pressing them in
Hardware:
The author remixed this model.
I changed the male side of the insert to be easily removable, with out he fear of breaking anything
