Is there a 10mm of this, and what are you using as lower z ?


One of my favorite additions to my mendelmax. Thanks!

Is there any way you could create a 10mm version of this?

Mendelmax Z Top with bearing mount for 10mm Lead screw and 8mm rod
by Bcrowe

This hole, for 608 bearings is to large.

Yes its larger so as not to fully constrain the wobble ... However most people including me stopped constraining z threaded rods a long time ago as it actually degrades layer alignment.

Lovely object, I am working on the same kind of object, however, I will never use a 2nd constraint for my threaded rod. Z-wobble galore!

I've always thought the MendelMax should have the threaded rod constrained at the top. I'm going to look into using this to minimize z-wobble, thanks for the contribution! Do these bearings fit your part? http://www.amazon.com/Bearing-Shielded-Greased-Miniature-Bearings/dp/B002BBD6X4/ref=sr_1_sc_2?s=industrial&ie=UTF8&qid=1371965327&sr=1-2-spell&keywords=608+beainghttp://www.amazon.com/Bearing-...

Yes, those will work.

Sorry, those bearings are Misumi p/n B6900ZZ. The dimensions are correct 10x22x6. Thanks

I'm using (2) Misumi p/n A6700ZZ which are 10 mm ID, 22 mm OD and 6 mm wide. I'm sandwiching the bearing with 26 mm OD thrust washers and then (2) shaft collars to lock the lead screws in position. Thanks for your time.

Would love a version of this for 10mm rod + bearing

I will need the inside and outside diamater of the bearing you will be using.
