Here are some pictures of my DIY rotary attachment for my K40 laser. Total cost was about $25.00
Thanks. It’s a combination of a couple of designs that werew on thingiverse along with my own design changes. Was going to use 2 steppers, but found it works juyst fine with one.
That is really cool. I was just recently thinking about/wanting to build one myself, but hadn’t got around to designing it. This looks great. I’d imagine that the 2nd axle should be movable though, to allow different sized objects in it (e.g. small objects won’t house on the wheels properly & larger objects will sit too high). Overall absolutely awesome though.
I am currently building another one that will be adjustable between axles as well as having an adjustable height roller for things like the neck of a bottle.

Looks great. Pretty much what I had in mind, the other axis moveble as Yuusuf said. my question is, why 6 wheels? An object you put on will only lean on 4, and in case of any imperfection, this will only make things worse… But I may be wrong, of course… What’s the OD of the o-rings? Did you calculate these from your Y axis?
This rotary attachment is so simply great, I give +1 
The extra rollers are for doing shorter items. I did not calculate anything, just made the wheels to what looked good, I will calibrate it once I have it installed.
Any plans to post the build?
The aproximate diameter of my timing sprockets with a belt on is 13mm. I guess I’d have to do some reduction if I want to just plug the motor with the same steps/rev without any further calibration, as 13mm seems too small to me. Say 2:1 and use 26mm DIA wheels (i.e. 20X3 o-rings). Unless there’s an option to do the calibration within CorelLaser, but I couldn’t find any option to do that…
Thank you to all that have liked this project, feels good to know others like your work. I need to gather up all the files I used and make a complete set for uploading to Thingiverse, as this is a combination of two other designs and my own mods to them. It should be up by Friday, but I will let you all know when I put it up.
@funinthefalls It is a great design/project & for around $25 is pretty good. Did you 3D print all the white plastic sections?
That’s awesome!
nice work and great idea
That’s cool !
@Yuusuf_Sallahuddin_Y No, all the white sections are laser cut, the red is 3D printed.
@funinthefalls Sweet as. Very nice build.
Any update on this one
Sorry, forgot all about posting the files for this, will try and do so this weekend.
