Anet A8 Spool Holder on pillars

This spool holder used the pillars and the two existing holes to fix this thing, the required space of your 3D printer are now reduced.

I create this spool holder because my 3D printer is inside a custom box where the space are limited (modified ikea LACK table)

Extra required part:

This Thing contain two parts from "SpoolHolder ANET A8 by Madjestik58":
- BOLT with a custom 19mm square hole in the middle
- NUT (original)
