Tippe Top with peg

Tippe Top with peg by bmcage Dec 9, 2012

Description

Adapted from the original thing for printing in one piece, as well as some other changes to make it actually tip when printed in one piece (oblate sphere). Two halves on one plate or the entire thing. As bonus, same for original. Sanding needed!

Note that this is actually the tippe top according to the 1951 German patent. First patent of 1891 does not have a cylindrical cut-out.

ProTip: print one at 10% infill and 1 extra boundary layer (=normal top ) and one at 95% (=tippe top). Give the one of 10 to a friend, and tell him to make it tip like you do yours :-)

Thanks for model! This one works great with Magenta PLA, 0.25 Layer on Cubify Cube 3nd generation. A little sanding was needed,

Did the 95% at 100% scale.
Now have made 100% filled at 100% scale.
Tried both on smooth and 'rough' surfaces - no good.
I bought a set of 3 different sized wooden ones from, I think, Aliexpress. Work very well. Tried copying them as exactly as I could, and variations thereof. but have got absolutely nothing to work.
Going to try this one at 1.2mm walls and 80% fill just to see...
I'm using Diamond Age PLA,
If the 80% doesn't work, might try another 100% fill using a very different PLA - Polymakr's PolyMax PLA.
Then, perhaps, your hollow one.
Note that my other tippe top (http://www.thingiverse.com/thing:38459 ) works great for me too. I print that with a top and bottom half

Instructions

[update 10 dec 2012] You need to follow parts of these instructions to obtain a working tippe top.

Other tipping tops: thing http://www.thingiverse.com/thing:38459 and http://www.thingiverse.com/thing:45822

1/ The tippe top needs a correct weight distribution to work. Printing at 95 to 100% infill should do the trick. I print at 95% to correct for unaccurate feed thickness and it works great

2/ The tippe top tips due to the friction force. It is hence important that the surface is sufficiently smooth to allow for tipping. I use sand paper 100 to remove unevenness. If there is a ridge on the surface due to the print, remove it with a dremel tool. If the tippe top is "jumping" from bubble to bubble, there will not be enough friction to tip.

For the same reason, the layer thickness should be low. Like this rolling and slipping is more guaranteed. I used layer thickness 0.18 mm on my replicator.

3/ Try to print in one version. For this, use external support. You can print with the peg down or the head down, both will work after removing the support and sanding the surface. Note, if you print with head down, the heat on the peg might distort it while printing it.

4/ there are different files here. The scad has options to produce all of them. Original is a form close to the original, thing http://www.thingiverse.com/thing:10291 Nopeg and peg should both work, single plate and full versions given. On trials, I cannot determine which one is actually better :-)

5/ The LARGE version is like the normal version, but with a shorter stem as jumping on a high stem is impossible for a heavy top. You can scale the LARGE version normally to whatever size you want. The large version is harder to spin, and uses a lot of plastic. However, you won't be able to buy such a large tippe top :-)

What material?
All materials will work, but pictures is ABS.
However, it's based on weight distribution over the tippe top, so you need to print with high fill (95 to 100%)! Differences in fill WILL change the tipping behaviour in ways I would have to calculate to predict.
Thanks. I've tried PLA, 95% fill, 0.1mm layer height, much sanding. No joy. Guess I'll try 100% and will report back.
BTW I slightly adjusted your SCAD file to give a much smoother surface (no change to dimensions). Also ran the resultant stl file through Netfab. Happy to send it to you it you'd like to have it.

Hollow Tippe Top

Ok, 95% should work. Depends a bit how big you did it to know how fast you must rotate.
Take into account that tipping is due to friction, so make sure there is enough friction on the point of contact. For example, tipping on a rough floor is easier than on a smooth waxed wooden desk. So, a smoother surface on your STL might not be better :-)
Even if no tipping, at 95% it should move towards tipping, so some precession, for example going flat (90 degree tip).
Send your stl to: benny dot malengier at gmail dot com. Adjusted SCAD also welcome!
