Ultimaker Original End Cups

Recommended Posts

Hi all, i am in the process of building the Ultimaker original, and seen some posts that the wooden end cups of the shaft creates some unnecessary friction, i have this idea as per attached, what do you think about this idea from your experience, will i have room for a collar on the inside of the printer ?

Thanks for the reply, i have seen these kind of modifications and to be honest i do not like a rotating shaft to have any end friction at all, my idea is quite simple the bearing is fixed from both sides at the outer part of the bearing with screws to the wood so there is no movement at all in the bearing in and out, and then the shaft is fixed with 2 collars, one from the inside and one on the outside both collars are closed completely with the inner part of the bearing so there is no way that this can move either side. My only question is the space on the inside as i do not know the exact position of the gears on the inside, so far i did not find any 3d drawing of a complete original ultimaker so i can have a look on the inside positions so if anyone can provide me with such drawing or pictures i highly appreciate it.

Thanks in advance

Are you making your Ultimaker Original from the Ultimaker kit? If so, the included smooth rods are not long enough to add outer collars. You would have to purchase some longer rods. Once you get to that sort of commitment, you might as well do the direct drive mod as well. In any case, you could also just fix the rods to the inner ring of the bearings with a spot of solder or glue and make a domed end cap that does not touch the rods but keeps out the dust.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
