So I have some thoughts on this, for the insert, the bolt hole should m4 and add a bit of width between the holes for 1mm shims on either side of the idler.
Then you could use the stock idler from the TTpro

Ok I will make v2 for the stock idler, thanks for commenting. Otherwise the mod fits ? alignment is good ?

Cool Thanks! Yea everything looks good otherwise

Ok there is a insert-D4 version, you can try it out :)

Printed the D4 version, Stock hardware fits now, you only need 2 m4 x 1mm thick washers to shim the idler.

But there is another problem, if you push the tensioner bracket into the extrusion so it sit flush, you lose a lot of Y travel because of the zap straps that hold the belt hit the bracket.

Alright, thanks for testing. I think I see how I could solve this. there is nothing obstructing that goes in the direction of the 4020 extrusion on which the bed is traveling on ? I guess thats where the bracket should be fixed at and extend on side at the end of extrusion not alongside on its end. I will try to adjust the file when I have time.

Hi Patrik,

Thanks for this design! I have printed the parts, but have not installed them yet as my assembly of the TTPro is still in progress. However I see that there's a problem with the bracket and was wondering if you've had a chance to fix it yet. Also, I would like to modify this concept to adapt it to the X axis gantry... Would you be willing to share the Fusion 360 files (or some other editable format) so I can work on it?

Cheers,
Fernando

Hey. I havent found time for it yet. But mainly because I was waiting for my TT pro to arrive and once I can measure and see for myself, it will be easier to design it properly. I have actually got it just a few days ago and found the time to build it today. So it will take some time still. I am designing in Rhino, not sure which format I could export to that would work for you. If you find this out tell me which format you want and message me your email address and I will share

Patrik,

You should be able to export your files from Rhino in IGES format. That should work for me in Fusion 360.

I get it about assembly of the TTPro... I have mine all laid-out, but haven't started assembly yet. I really should just start and stop waiting until I have all the little parts and upgrades/add-ons I want!

Thanks again,
Fernando

sent to your email just now.

Thanks Patrik!
