Our recent update to the Sovol3d SV06 Plus printers and change from PLA Pro to PETG, has had a side effect of our tolerances for assembled parts (parts that fit into other parts) can be much tighter now.
For the spinning wheel bobbins, I had a tolerance of .3mm but for the new machines that was too much. I've been able to reduce that to just .1mm, making for a much nicer fit.
While this better fit could mean we might be able to forgo the adhesive, I feel it creates a better value for our customers to continue using the 3D Gloop for PET/PETG.
