Like many, I broke the figure at the waist trying to release the ab crunch. 
I decided to teach myself 3D modeling and printing in order to make a replacement piece.
I&apos;m sure it could be further fine tuned but once I got to v7 I was satisfied. An added bonus is that, while it doesn&apos;t fix, it does help the Alt mode transformation a bit. With extreme care and patience you actually can get everything tabbed in and all 6 wheels sit flat.
I suggest printing in ABS. It is easier to sand and the little bit of flex inherent to the material seems to hold up better than PLA under stress.

<div>This custom lens re-housing is optimized for &quot;Helios-44-2 58mm f/2 (M42 mount)&quot;.
The history, features and specifications of this famous Russian lens are very well known, so there is no need to add a description.
This lens housing has a front diameter of 95mm and the focal gear is also applied with a 0.8M standard gear pitch applied to cinema lenses. (Focus &amp; aperture gear Outer diameter 81.6mm / 100T) The design of this lens housing is more convenient to use in combination with a follow focus device. It can be a little inconvenient to operate the focus ring by hand.
Designed to be secured using M4 standard grub screws (22 pcs.) and M4 *12mm standard screws(4 pcs). The filter step-up ring used on the front is designed for easy use of regular circular filters. (Front standard filter mounting screw, maximum 82mm, variable ND filter can be used up to 77mm)
I&apos;m tired of repeating similar modeling every time, so I&apos;d like to apply experimental and practical ideas one by one. (Of course, it can be roughly finished as a side effect.)
This time (some lenses that have trouble connecting and using polarizing filters or matte boxes due to the rotation of the front of the lens) I wanted to try a design that improves the lens front so that it does not rotate. (Helios-44-2 is not this type of lens, but there is currently no suitable lens in my list of lenses) and I also considered a lens housing in a way that is not affected by the length change of the front of the lens due to the focusing operation. This is not an inner focus lens structure in an optical sense, but it can be expected to play a role in mitigating changes in the length and center of gravity of the lens according to focusing operation.

4/14/17- The D-Shaft Hole was not perfectly centered on the one piece sun. Fixed this issue with One Piece sun V2. Uploaded the Rotating Base <a href="http://www.thingiverse.com/thing:2166517" rel="nofollow">http://www.thingiverse.com/thing:2166517</a>
2/27/17- I designed a one piece sun gear for this, one version with a large drive gear on it and one version with a 5mm D shaft hole, the one piece sun gear is compatible with the 3 &amp; 4 module planet gears. if your using the 4th module you may choose to use the #2 sun gear in module 4 in conjunction with this. Using the one piece sun is a good upgrade for this as it cuts down on backlash.
I designed this gearbox for my Modular Robot Arm Project, check it out! : Original model: <a href="http://www.thingiverse.com/thing:2105057" rel="nofollow">http://www.thingiverse.com/thing:2105057</a> EZ Print model: <a href="https://www.thingiverse.com/thing:2153317" rel="nofollow">https://www.thingiverse.com/thing:2153317</a> Lazy Susan Base: <a href="http://www.thingiverse.com/thing:2186716" rel="nofollow">http://www.thingiverse.com/thing:2186716</a>
Both models are 100% compatible with this gearbox (&amp; the 66.46:1 gearbox) and each other
Assembly ------------------------------------------------------------------------------------
Align the planet gears in order as shown in the main picture, insert a sun gear, Snap Ring Gear #1 on, Inset all sun Gears, snap the other 2 or 3 ring gears on, also, you will need to close the gap in the rings before you spin this gearset or else it could skip teeth and get out of alignment, for this i have included the ring closures, that fits over all the rings
For any instructions i may have missed, please refer to this : <a href="http://www.thingiverse.com/thing:2081324" rel="nofollow">http://www.thingiverse.com/thing:2081324</a>, this gearbox is very similar in concept.
How it works ------------------------------------------------------------------------------------------
When you rotate Sun Gear #1 (The sun Gear with the D-Shaft hole) The Planet gears orbit that gear causing Sun Gear #3 to rotate at the exact same speed as Sun Gear #1
Now, When the Planet Gears make a full 360 Degree rotation around the Sun Gears, Ring Gear #2 ( and the Optional Ring Gear #4) will move 27.7 Degrees, ( 2 Teeth)
The other important thing to realize here is that Ring Gears #1 &amp; #3 will be at the same potential and Ring Gears #2 &amp; (Optional #4) will be at the same potential
The use of Ring Gear #4 and the 4 Module Planet Gears is optional and used to increase the amount of torque this gearbox can transfer, as well as to decrease the amount of (radial?) load on each gear, think of it like a door hinge. When you use the 4th module you should re-use Sun Gear #2 to space out the planet gears within Module #4
////----------////----------How to Design your own--------////----------////----------////---------- If you would like to design a gearbox like this to integrate into your own project, just follow these somewhat complicated and poorly written instructions.
You will need two planetary gear sets, the closer the number of teeth, the higher the output gear ratio will be. The following design constraints are very important:
But First, design tips:
<ol>
<li>The more planets, the harder it is to meet all the constraints.</li>
<li>using gears with lots of teeth can achieve very high gear ratios(500:1+), and higher ratios than i have designed have been achieved by others, such as Emmet.</li>
<li>Gears with a lower pressure angle have much less friction, and last longer, but aren&apos;t as strong. I am experimenting with newer designs with 20 deg pressure angle and they&apos;re very promising.</li>
</ol>
You will need to study the gear tooth combinations that work properly in a planetary gearset, keep in mind that not every combination of gears will fit together, and not every combination that fits together will allow for evenly spaced planets (and that IS necessary), to find gear combinations that fit these two design requirements, use these two equations.
For Figuring Gear Combinations that fit together: Teeth_Sun + (Teeth_Planets*2) = Teeth_Ring_Gear
For figuring if the planets (pinions) can perfectly evenly spaced: (No_of_teeth_sun + No_of_teeth_Ring) / Number_of_planets. has to be integer. (Whole Number) for both Planetary Gearsets
Keep in mind that those two equations will not prevent you from making planet gears that overlap, heres a quick tool for that: <a href="http://www.thecatalystis.com/gears/" rel="nofollow">http://www.thecatalystis.com/gears/</a>
Once you have decided on a number of planets and your two planetary gear combinations that you would like to use you need to model the gears, You will need to go off into your CAD program. When modeling the gears the most important design constraint is keeping the planets from each gearset at the same center to center distance.
Use the following equation to align the planets from the two planetary gearsets with one another: Planetary Gearset #1 (Sun Gear Pitch Diamerer + Planet Gear Pitch Diameter) Must be equal to: Planetary Gearset #2 (Sun Gear Pitch Diamerer + Planet Gear Pitch Diameter)
you can set the pitch Diameters equal in your cad program by adjusting the module(the number of teeth per mm) of one planetary gearset in contrast to the other. FYI the pitch diameter of a gear is the size of the circle that is made when it meshes with another gear. I.E. if the gear was a cylinder, rolling against another cylinder.

The model attempts to capture many of the details of Han Solo&apos;s DL-44 from Star Wars: A New Hope. The reference images I used came from blurry screengrabs and Lucasfilm archive photos online. The model is printed in many parts to maximize detail and ease of painting. Some parts require support and glue to assemble.

Notes (5/10/16): 
The heatsink is problematic to print. I printed it sideways such that the ridges are laying on the printbed. I printed with PLA support material, but soluble support material will definitely help it print better.

Notes (7/03/16): 
I added:

-Bolt Stop. 
-Sight cap screw (print 2 of this to fix the sight to the slide). 
-A modified slide with a hole to insert the bolt stop. 
-A sight 
-A sight sliceable measurer 
-A lateral button for slide measurer 
-A new grip with a rounded bottom, more similar to the original grips. Print 1 and another flipped for the other side.
