Weighted Base for 600% Size Arm - by LeisureLuke

Joel, the 3D Printing Nerd, made a 600% size articulating arm. This is a base that support that arm, mount 2x45lb weights, and mount 4x3in roller wheels. This is a functional, and very much matches the theme of the arm.

See the inspirational video here: https://www.youtube.com/watch?v=64wYYJFWZW4

Goals:
Mount weight for stability
Add wheels
Printable on Joel's Printers
Upscaleable
100% plastic. Besides the wheels, I wanted this to be fully plastic

Features:
Roller wheel inserts made for Universal Office Chair Wheel Replacement 3" Chair Caster Wheels
Hand tool to remove wheel inserts
Optional Extra M14 threats sticking up in 4 corners, or smooth finish.
Quite small considering the rear arm mount and 45lb plate holder space
Will be easy to roll, and can add up to 90lbs weight.
I think it'll all print easy except for Crane PartA... This will be too big for CR30 I think, but other 3D printers should do it just fine.
MINIMAL Tolerances built in between 0.05mm and 0.1mm with the intention of upscaling.
All interface surfaces match previous design.
All M14 threads have 0.1mm tolerance on both thread sides, which works well for me.

6 pieces, 3 bolts, 1 nut, and 4 floor (wheels or leg) mounts is all that's necessary for complete build.

Extra Pieces:
Hand tool
Leisure Luke's Gym 45lb 1/6 scale weight
Floor Mount Legs (rather than wheels)

Uploaded 2/10, likely to have a few changes after printing the small model version.
Currently printing and testing. If anyone wants I'm happy to customize this, edit it, make changes, add parts, just ask :) Happy to spend another day making it cool, adding your logo, etc. Props to Igor83 for the original design!

Joel, if you can see this... High Five :D
