Could you make one with the belts at the correct level spacing (even) for those who use a 16 tooth idler?

I am building a Core XY and would like to incorporate this design in it. Would you share the CAD files please?

Hi Buj

I dropped you a private message

Well, this is not working for the MK3 at all. Its not only running into the frame on two sides, the belt is scratching on the underside and... ah well look at the attached pictures.

When did you download it?

The day before I wrote the comment

How much clearance is there between the bottom of the carriage and belt for the MK3?

I haven't put together my Bear Upgrade yet, just printing the parts for it now. I've been taking measurements and been toying with designing a Y-Carriage with tensioner built in like you, but one of my issues is determining how much I can add to the height of the part before it starts rubbing.

The issue I'm seeing is that your part comes in at 27.8mm, but comparing to my measurements, that's too tall and would result in rubbing. The most I can do is 25.5mm before I risk the belt rubbing.

Hi Hotpocketdeath

the belt is indeed close to the bottom of the block but there's still ~1mm clearance

Very nice work! Thank you :-)
