I created this large 34x18.5x8cm box featuring an elegant wave design, printed in two separate parts which you can easily glue together at a special rim. The design journey led me to choose PETG material, despite its notorious tendency to warp, because of its strength and durability for such a large structure.
The box’s construction was an interesting challenge. I’ve included mouse ears in the design to help secure the print to the printer bed, a crucial step in managing PETG warping. I found keeping a stable room temperature, or using an enclosure with controlled temperature, also made a significant difference.
My material choice was Prusament PETG Signal White, printed with careful attention to air temperature, aiming for around 32ºC. This approach minimized warping and resulted in a clean finish.
Connecting the two parts was a task of precision; I sanded the rims and used Kapton tape to align them perfectly before applying 10-minute epoxy to secure them together. The Kapton tape, being impervious to epoxy, was instrumental in ensuring a flat, seamless bond between the pieces.
For those preferring to use PLA, I made additional gcode files specifically for the MKS3 and MINI printers, omitting the mouse ears since PLA is far less prone to warping.
I hope you find this project both challenging and rewarding!
