A 8mm Z-top that has a 608 Bearing Leadscrew capture and press fit rod clamp.


This parts requires the top Z extrusion to be tapped like the original MendelMax.

No reaming necessary for the rod clamp on a well calibrated printer.

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.

jib - in reply to Toruk

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.
