About this 3D model
I designed a pen holder based on a Roman column and printed my LOGO on the bottom. I have uploaded the source file and can modify it to the size you need. This is an S size size: Height: 90mm Width: 80mm The PLA printing I used set the bottom surface to 5 layers and the fill to 10%. The other parameters are the default parameters of Bambu Lab. I also designed an L-sized one to provide different usage scenarios. You can visit my homepage to view it.
