K8200 frame extension with spool holder

I had some trouble with breaking filament while printing higher objects. I think it's because of the low temperature in my workshop and the small radius the filament is bent.
So I designed this frame extension to get some distance from the spool to the extruder inlet.
It's basically a socket for the frame with a slot-compatible extension on top. The right side is extended to allow a spool to be mounted, the 3 slots on the other sides can be used to mount accessories.
Future extensions planned:
-dust remover addon
-second spool mount on rear side (only longer rod needed)
-eventually: webcam mount
-eventually: light mount
Printed in PLA with:
-concentric top and bottom fill
-2 shells
-3 layers (add 2-3 when you're printing slim)
-10% hex infill (15 if you expect more than 2 kg weight)
-NO support (just make sure you're printing not too hot to avoid bridging issues, I used 190 degrees with good results)
The fit is quite tight, the 2 screw holes in the base were not needed in my case.
