Danny's mods incorporated!

A project log for Thor

OpenSource 3D printable Robotic Arm

Time ago, Danny made some modifications to largest pieces, splitting them and making them printable in 180*180mm bed area printers.

He made an awesome work, and I wanted that modifications to be in the main repo, so I added it! Also, I migrated the design to FreeCAD in order to have the source files too ;)

EDIT 21/12/16: I have migrated another 2 modifications to FreeCAD :)

On the left, my remix of Art4Body modification made by Danny. Designed for low height printers, thank you again Danny :)

On the right, the BaseBot modification made by Ctrl-Alt-Dude for 190*190mm print area. This will allow more users to print Thor. Thank you too! ;)

Are you having issues with other pieces?

Season's greetings for all!

Some new idea I have. When you look how it is printed in 2 parts, you could actually make it extendable with 2 or additiponal 2 rings to make the arm longer by choice.

For feedback I have a small issue with one of your parts.

The thing is that my 3D printer is in my living space and I don't trust it to print when I am away.  If I print this main part then the print is 19 hours. So I printed it in 3 parts then glued it together.

Back then I did not have the motors yet. But last week I tried to insert the motors as a trial and discovered that one I can't get inside.  I have been wondering how to modify the original design to make assembling more easier and have some cooling fans openings, but I am not a mechanical guy and ran out of inspiration. Creating a 3D model is easy, but creating a 3D model that also mechanically works and is easy to assemble is very hard!

The fact that this is a 19 hour print model prevents me to use trial and error.

I have one of my posts here that shows an image of the motors not fitting (down).

If you feel inspired to redesign that part, then it would make me happy.

Something would be nice if we could just insert the motors from a back panel. But I think it wpould lose structural entigrity.

Yeah, I really understand you hahaha

That piece has its own history... and it ended being a big solid part, hard to print and hard to fit the motors inside... I'll study the way to split that piece! I have some ideas right now :P

I'll keep you updated! Thanks for the feedback :)

The biggest time a 3D printer loses is printing the support structures. If you can prevent 90 degree angles to occur and have slopes instead then the 3D printer could gaain much more time.

These new additions looks sexy!
