Remixed in Bambu Studio (just by cutting and moving parts) to create a version with space for 2 pens (one for use now as well as the next one). The pens were taking up more space in the fridge drawer than they should, but didn't need the needles to live in the fridge too - and when I'm travelling I use

for needles. There is space for alcohol wipes at the end still, and space in the top for the instructions if desired. 

The 3MF has the text separate so it should be easy to adjust to whatever you want.

Thanks to https://makerworld.com/en/@TomSmith for the original.

I only really print in PETG but I see no reason why it shouldn't work just as well as the original in other materials.

Let me know if I've done this wrong - it's my first upload…
