Hello
This is a pen holder for 28 pens (for my fountain pens in my case), plus a small area in front for anything you want (more pens, eraser etc…).
I've printed one part in PLA wood and the others parts in PETG (translucent). With the A1 mini, it just fits on plate.
There is no sharp angle in order to avoid bad stripes on pens.
The critical part is the column printing because I wanted circular columns. Raft is needed as well as slowing down the speed. It worked for me up to 90mm height; in the proposed model, the column height is 77mm (I believe the right height for the pens). Yet this height can be modified easily in the Bambu lab slicer (scaling in Z).
Printing columns lying down horizontally doesn't work properly (or columns need to be sanded).
This is my first 3D model, I hope you will enjoy it.
