im afraid after reading the comments im still unsure of the scaling. I have downloaded the files from this link: https://www.thingiverse.com/thing:2839354 as of May 10th this year and some of the files say V2 and some dont.
The ones i am printing that say v2 are: Top_v2.stl & SpiralV2.stl, the rest never had V2 in the name and they all came from the same zip i downloaded. Im planning on printing the crown and shell file from your design.
My question is, do i scale the crown and shell to 103.4% or do i leave it normal with the files that im using?
