Great, thanks :) (edited)

Thank you for this design. It's a very easy print and has, so far, worked well. I printed the threaded insert option in Sunlu PETG.

Printed in PETG, thank you!

Prints well. Slow, but lattice structure is indeed very resistant to shrinkage. Does the work as advertised.

I printed it using 0.8 nozzle and 0.55 layer height. Printing it using 0.4 nozzle would take too long as the columns are a lot of small movements. Still, a worthy tradeoff.

Fits my "old" swatch slides (80mm x 30mm x 2.3mm) perfectly: https://www.thingiverse.com/thing:3341363

This is great! Nice job 👍
