Prusa MK3 Roller spool guide

I got a 3D printer and had a surplus of IKEA LACK so I used a great custom known to make it an enclosure.
However, I wanted to load the filament from underneath the enclosure, so I used the great spool roller from the remix as a good guide roller.
It worked very well, but when I laid marble to reduce noise and vibration, this roller hit the upper LACK.
Therefore, the roller arm was redesigned so that the shaft could be lowered by about 1 cm.
Use the original remix for the roller parts other than the arm.

I also made a guide ring base that looks in the middle to prevent the arcuate filament from hitting the ceiling.
The base has holes of 12mm, 3mm and 12mm in depth, and you can use the guide from the remix source.
