K250 - Ultibots Kossel spool holder extension

thingiverse

I received a fantastic kit from Ultibots (item 456659) that caught my attention right away! Unfortunately, I noticed some of the spools were having trouble fitting through the holder. To solve this issue, I took the initiative and designed a straightforward extension to improve the bearing used for the wheel's rotation. Here's what you need to do: Just print out the kit and lightly sand down the outer surface to ensure a smooth spinning experience.
