Hello!
No supports are required for this print since there are 2 pieces.
Print the disc first!
The frustum (a new word I learnt just for this write up) was printed with the top on the plate and a brim for better plate adhesion.
A pause is required after printing 9mm (or before the start of layer 46 if printing at a layer height of 0.2mm) to insert the disc. There should be enough clearance between the disc and frustum to drop into place but there shouldn't be any movement of the disc within the slot once the print is done.
The author marked this model as their own original creation.
