Reef Factory smart roller

This Mod is to accommodate a large fleece roller refill from Bubble Magus. Version 1 & 2 will allow the included cardboard tube to slide over this 3D part. Version (1) is to substitute the main shaft from reef factory. Version (2), is so that you can use the original shaft from Reef Factory and being also able to slide the tube in place, but this will require to add some glue so it won't move over time. Because most people aren't able to connect this roller matt to the app, it doesn't matter on having to replace the main drive shaft for version 1. I recommend printing this in PETG……Thanks and happy reefing
