Remix of REMODELED Flying Tourbillon Model 1.5 by CMPND3D

Note, I posted this on Thingiverse as a remix here:

but had a problem associating it with my list of account models there so I moved it to Printables.

REMODELED Flying Tourbillon Model 1.5 by CMPND3D:

which was originally based on the Flying Tourbillon Model 1.5 design by A26 (which I haven't examined):

The original design CMPND3D based the remodel off of by A26 is also posted here:

I included a printable 608 bearing in the Fusion 360 model of the assembly from DrMcWoofies:

(I used this 608 bearing only in the Fusion 360 modelled assembly but ended up using an actual metal 608 bearing in the physical print and haven't tried using a 3D printed 608 bearing)

I began by creating a Fusion 360 model to generate and assemble the STL files I generated from the OBJ files posted by CMPND3D in order to make sense of the overall part functionality and assembly.  After printing the model out and getting it functional for up to 20 seconds at a time, I believe the assembly of STLs in Fusion 360 is correct to the best of my knowledge.

I remixed a few parts along the way, removed some logos for my preferred aesthetics but I left the original files with logos if that is your preference.  I also remixed a couple parts to make them function better after my experience working with them.

These are two parts that are reworked:  
1. Retention_Arm_Bottom_Modified.stl  (Print this one instead of the original as it fits much better)
2. Anchor_Modified.stl (made it taller to engage the roller better; I did not need to print the anchor_plus_pt5mm file)

update 07/22/2022- I recently printed the stand_no_logo_modified,stl and found that if I tapped the hole for an M4x8mm into the “base” plastic hole it works but really needs to be a little thicker to bury the M4 screw head in the plastic stand so it doesn't touch the table by about 2mm should probably do it.  I would make the hole for the Allen head M4 screw head to fit easier inside the stand since the head is snug in the hole and open up the hole to clear the M4 threads in the stand so the screw fits freely in the stand hole.  I am guessing that 108% scale in the Z and maybe 103% in the X and Y would allow an M4 screw head to be buried in the stand…  Also, I had a new record of around 24 seconds so far (not bad for using slightly bent axles).  The Tourbillion seems to work better for me with the screws left loose.  I do have slightly bent axles…

I did use large binder clips for axles which were 1.8mm in diameter.  My binder clips were not straight from the factory so perhaps there is a better axle option.  The holes in the Frames were a tight but I opened them up carefully for the cut binder clips.  The holes in the escapement wheel, Anchor, and the balance/roller assembly seemed to work OK with this 1.8mm diameter shaft.  

I printed the original Anchor but realized it was a little thin to reliably engage the roller so I modified it to make it taller.  The Retention Arm Bottom just was too short to stay in place.  It would have needed to be glued in so I made the tab longer and put a hole in it so it stays in by friction and hopefully will not interfere with the stand screw.

I did end up supergluing in the balance spring as it didn't seem like it would stay in by itself for very long.

I printed out of eSun PLA+ and had it running for maybe around 20 seconds or so.  Not enough to turn a complete cycle before jamming or running out of energy.  This is the first time I printed one of these so I am happy it works at all.  It is more of a conversation piece.

I tried to split the base into two parts to avoid printing support with the intention to glue them together but the split was on a nut slot.  It worked but is not very strong so I didn't include the STLs for the split base but my poor attempt at splitting the base is in the Fusion 360 model.  The idea to split the base could work but needs improvement in its execution.  If I did it again, I would print the original base with support or remix the base to get rid of the retaining nut slots.

The nut retaining holes make the parts weaker so don't tighten the nuts much.

All in all, the project that was interesting to build and nice to see work, even just for short bursts.  The tolerances were a pretty tight throughout but didn't take too much effort to sand or file make the parts work.  If you decide to build this, be prepared to tinker along the way.  I wasn't disappointed as I did get it to work for up to approximately 20 seconds at a time which demonstrates the concept.  

Thanks to CMPND3D for sharing the OBJ files for the remodeling effort.  I'm not sure how it differs from the original by A26 as I haven't looked at that closely but thanks to A26 for the original design this CMPND3D's model was based on.

Enjoy!
