First of several palette boxes for Kuretake watercolour pans. The edges are not rounded - a version with rounded edges will be available shortly.
PLA works, but IMO results are nicer in PETG. The box has a ridge on the top which the lid slides onto with a mild friction fit.
After printing, the corners of the ridge on top of the box may need to be trimmed with a sharp knife in order for the lid to fit. Additional post-processing knife work on the lid and/or the ridge may be needed to obtain the desired fit for the lid. Variations in fit can be expected, depending on printing parameters and accuracy.
The author marked this model as their own original creation.
