It is recommended that you store your pens with the nib downwards and I wanted the challenge of creating my own holder.
Project on Cricut Design Space
This pen holders holds 48 Cricut Fine and Gel pins tip down as recommended.
Finished size length 21cm, width 9cm and height 5cm.
It is made using Kraft board but you could use other card. I did try with Basswood but had issues cutting the pieces that hold the pens.
I created this organiser to hold my glue gun and a section to hold a note pad or other useful tools.

There is a useful handle to to pick it up and move around.
Approximate size width 14cm, depth 5cm and height 14cm. Each section is 2.5cm.
It was created using Plywood Sheets, 300 x 200 x 1.6mm Unfinished Basswood Sheets Board for Woodcraft Model, Crafts, Painting, Engraving, Stenciling, Home Decor by Binswloo (purchased on Amazon). You don't have to use basswood, you could use Kraftboard or other thick card and multiply the layers to give you the thickness you need.
