This design is a new version of my box to securely send 25x25mm glass slide samples by post.
Compared to the last version, the profile has been modified to hold the slides more securely, the holes are designed for hot melt inserts and TPU foam is used on top and bottom.
The TPU parts are sliced using no wall and no top layer and 20% gyroid infill with ninjaflex 85A TPU
