Summary

I was spending way to much time at my computer and my trackball arm was starting to ache at night because of it. I decided to create a device to angle my trackball so my arm could be in a more natural position while I "moused about". This is the result. The Logitech M570 trackball has a few underside features that allow it to be held in place from below. The battery cover plate must be removed to insert the unit into the holder. I also carved out a hole to store the plate so it doesn't get lost. :-) As I printed it, the unit fits snuggly into its place, to the point that I can even hold it upside down with out it falling out, but I wouldn't count on that. It stays put nicely in its cradle .

Plastic on desktop surfaces slides around a bit too much so you will probably want to add a rubber bottom (jar opener?) or a cloth which is what I use right now. Also the cloth can be folded to create a wrist-rest to add support for the hand. One could also secure high density foam, gel, or silicon material to the top surface as needed.

The space between the table "pad" and the trackball mount needed something to make it more interesting and improve the aesthetics. I've always been fond of MeshMixer's tree shaped support structures and decided to incorporate it into the design. I then stuck a few critters in among the trees. These are my sources.

The blender file is a huge mess of objects involved in creating this. I'm including it in case one wants to do further remixes. If only printing is desired, just download the stl file.

If you like this and are feeling generous please consider feeding Foxpup. -> bitcoin:1KTAf3EM1kNWxpKrSSFqbESqYQZf2PAXdm Any amount, large or small, is appreciated, but only give if it brings you joy, not out of a sense of obligation. All the good ideas that Foxpup gets come from the Author of the universe and Foxpup is just passing them on :-)

At the request of one user, I have provided a version with no trees or critters underneath, so the user can add whatever is desired. I strongly recommend putting something there to provide adequate strength. In that spirit, I also added a version with a simple support. It isn't pretty but it is functional. Lastly I put pass-through holes in all products (V2) where the trackball "stud" is. I did this to make it easer to pop out the ball for cleaning. The previous version is just fine and left in place as a reference, but I'd print V2 because of its improved utility.

I also added a low-poly version for those who would otherwise have trouble with the bitter gile.

Print Settings

Printer Brand:

RepRap

Printer:

Custom modified Prusa i3

Rafts:

No

Supports:

No

Resolution:

0.2 mm

Infill:

I used 15%


Notes:

I have acceleration set very low on my printer so this prints slowly for me. With a .3mm print head and .2mm layers this took me ~24hours to print. I would expect much faster prints for most others.

Post-Printing

Do not remove the support trees. :-) They are part of the product and provide cover for the critters within them. They don't provide much structural support, but not much is needed with a 60 degree incline. :-)

How I Designed This

I mainly used blender to do the shaping. Meshmixer provided the trees as support material. I also found the 3dconnexion space-mouse very helpful in navigating around in 3d space while designing. Netfabb-free was a great tool for cleaning up my work and helping make sure it is properly manifold.

Hi there! Nice job. Would you be down to sell me one of these designs?

Hello,

I am new to 3d printing and I am saving up for a printer. Would you be willing to print one of these off for me? I am a disabled Veteran and have nerve damage in my right arm. I can't use a regular mouse and found the trackball M570 really helps me a lot, but it is still at an odd angle to use. I think this would help too relieve the tension in my arm.

Thank you for any help you can provide and I am grateful that there are creators out there like you that are able to see a need and are able to fill/fix the problem.

Jonathan

Please PM me with more personal information so I can verify who you are. I'm happy that you like my creation and would be thrilled to help a Veteran who could use some assistance. :-)

I love this design, but I can't get Meshmixer supports to work on the blank one I downloaded. Could you possibly upload a version of this with the supports but not the animals?

I went into Blender and created a critter-less version of this stand that I also checked for manifold-nes. This should slice nicely enough in most situations. I could say the same with the V2 version of this stand that still has critters. Enjoy!

Thank you, the file you uploaded was precisely what I was looking for.

Glad to help, except those trees look awfuly lonely with nothing in among them. :-) I know I'm just being silly, but it seems kind of sad getting rid of them. :-)

Well in that case I'll just have to use the excuse that they are too small and it's tough to make them look that good because of it. Now you wouldn't want them to look bad would you?

That's all fine. I'm just glad you like. :-)

One of the files already has a support "panel" and no animals or trees. The platform that holds the trackball is at such a steep angle that normal 3d printing support material is generally unnecessary. The "panel" is there for structural purposes during use and not so much printing. Is that file suitable for you, or are you asking to keep the trees but omit the animals?

It's official, I'm not the only person on God's green earth that uses a trackball. I'll likely be making this soon.

Imagine the obscurity if you wanted one of these to be LEFT HANDED. :-) (Like Rodents of Unusually Large Size, I don't think they exist.) Actually, these things have gotten a bit of a beach-head only just lately. I actually walked past an M570 in a blisterpack for a fair price at WALMART. I love the fact that you don't need much desk area and you never have to pick up the mouse when you reach the edge of the table. (a dynamic I am no having to deal with again with modern VR equipment. When you reach the edge of your physical room, you have to back up and teleport forward to go forward in the VR world. - Wish I could walk on top of a trackball. :-) )

Make a hamster wheel with a solid floor for people, scale it up around 1000%, than sit back and wonder how the hell you're suppose to print that. After you figure that out, please make a post.

Got it, printed it, love it. THANKS!!!!!!!!!!!!!!!!!!!!!!!!

Glad you liked it. :-)

Could we get a version without trees and animals? It bogs down my slicer trying to get through all of that, and gives me a 14-hour print.

I have been unable to edit the model myself in OpenScad (the only modeling software I have).

I'll try to put something together for you shortly. :-) (Like before I go to bed tonight) <8 hours

Thank you. :)

Hopefully, one of the files I added helps you. Recommending :

LogitechTrackballStand-SimpleUnderstructure.stl

Enjoy!!

I should consider making a version with the critters in a lower-poly form. Much of the detail is overkill. When I slice it, I use Repetier with the Cura slicer and that works, but slowly. Other tools may choke on its current size. :-) My setup is only an 8GB-RAM quad core system but it is running Ubuntu and that helps me get the most out of it. I can imagine others struggling with the file size, especially with 3d printers with built-in slicers. :-)

That one works much better. And it gives me only 9 hours printing. :)
