If you ever wanted to improve your print results, you may have tried to dry your filament before printing. And then you start a four hour print and the spool wets itself during the time.

So, wonder no longer, here is the solution you are waiting for. A cover for the right side of the Core One, optional with a humidity sensore in the frame. 

Simply print the parts with a stopp at the upper magnet hole position, insert as many magnets as you like, continue printing. The 20mm screws are used to interlock the four side parts with their neighbours and the glass sheet. The 8mm screws make the build more sturdy.
