I printed this in PLA and the motor mounts did not fit. I tried forcing it a bit too much and ripped the wires out of a motor and broke one of the crazyflie motor mounts.
This takes an incredibly long time to slice with my (admittedly ancient) checkout of Slic3r. What did you design it in?
Also, thanks a ton for your contribution to my crazyflie's continued health :)
Shapeways failed to print the junction parts with the following message:
Crazyflie Frame V1.7 Junctions in Black Strong & Flexible
Reason: Thin walls
Additional information: The minimum wall thickness for this material is .7mm. Please thicken the walls of the model
In an attached image they say that the bottom (flat part) of the junctions are 0.4mm in height which is indeed < 0.7mm.
Could you maybe change the thickness to 0.7mm? I don't think it has much effect on the weight of the total frame.
Leave a message on my blog I might be able to have an alternative:

I'll probably use some thin sticky tape or just glue instead, since my order is almost complete and adding a few junctions will take another 3 / 4 weeks :)
I also have version 1.6.5 made. Which version do you think will be best to use for a beginner? At first I'd like to use the best protection, gradually working my way to flying without protection (except maybe some protection the bottom of the motors).
Fucitol I would advise v1.7 for starters as it provides a better overall protection (XYZ protection) than v1.6.5 and it adds a bit more inertia to the flie (makes it a bit more tame).
Once you are more experienced flying move to a v1.6.5 with washers on the motors. v1.6.5 is a light weight frame and provides limited protection (XY plane protection).
Note that I have not mentioned v1.8 this is because in my experience whilst v1.8 provides the best all around protection on all frames, if printed in PLA becomes very fragile and it lasts a couple of crashes only.
I am going to make some tests this weekend printing v1.8 in a different material so as to improve durability.
How much have you payed in shapeways. Have you seen my stuff in ebay?
|8-O Wow! Sci Fi. That is - Over The Top! Good Job! The photo, shadows and rock. Very cool. When's the movie coming out? ;-)
