Description
This is a bearing I designed specifically for one of my mods:
QIDI X-Max - Improved X-Gantry With Tensioners
It's similar in style to the commonly available IGUS bearings but I needed a slightly increased inner dimension (ID) to avoid binding of the Carbon Fiber rods I use in my printer. Normal steel bearings cannot be used with CF rods as the steel balls in the bearings would destroy them quickly.
I recommend dialing flow before you start so you don't underextrude or overextrude your prints, it's quite important:
Versions
I have included the following bearings for compatibility with more printers, available both as stl and step:
Print Settings
Print the bearings in the direction I have set them, supports should not be used. Print one and see how it fits with your rods and adjust if needed (step file is available).
I recommend using Nylon (PA) filament for these as it works great with both steel and CF rods, it has low friction and is very durable, no maintenance required, although it doesn't hurt to clean/wipe the rods every now and then.
Step Files
I have included step files if you need to increase or decrease the ID or OD slightly.
