Polydryer Shaft with 608 Bearings and a Side Handle

I decided to give it a try with a ball bearing shaft in my Polydryers to see if the difference really is that significant compared to a standard Polydryer shaft. And yes, it is!

I wanted to use 608 bearings as this is the only size I have and I do not want to buy other sizes/types of bearings unless I really have to. And I wanted a side handle so that I can easily guide the shaft straight down to its place when inserting a spool. 

Also many of the existing models have the bearing exposed to the spool. I do not like such approach because then it is not usable for narrow spools (e.g. 0.5kg). 

I decided to construct my solution out of three parts:

• Shaft with the two 608 bearings inside

• Side part with a handle

• Side part without a handle

I prefer to have a handle on one side. But it is up to you if you want to have the handle on both sides, or perhaps if you do not want any handle at all. Just print a combination of the side parts which you want.

The bearings fit tightly into the shaft, they are supposed to. You may need to use a bit of preasure to push them in depending on how much your filament shrinks. Should you need to remove them from the shaft, the easiest approach is to push them out using a pencil.

No supports needed.
