This is my holder/display model for pens/markers.
I used it for my 36 colpart acrylic marker set, which can be bought on Amazon.
I printed it with the following adjustments:
I printed it with Elegoo PLA+ but the Bambu Lab PLA Basic or Generic PLA profiles should work fine as well.
My provided model was built with 10mm tubes (inner diameter), so that everyone can easily scale it for their personal usecase.
(For example, if you need an inner diameter of 14mm, than just scale it by factor 140% on X and Y axis in bambu lab studio)
Hope you can enjoy my work.
