Gridfinity Needle File Tray for 3 Files

I liked UnoriginalElephant's original tray, but my file set only came with three files. So I created this for myself, but you may also find it useful, so I decided to upload it!

My files' handles have a width of 11.75mm, which leaves a tiny gap between them, I therefore recommend against using files that have handles that are wider than that. 
You are welcome to try it if you have larger files. I (and others) would appreciate it if you posted your results in a comment :)

Note that (like the original), the magnet holes are NOT pressfit-style. But I used some Blu Tack to fill out the space and keep the magnet in place.

I created this remix in PrusaSlicer 2.8.0. Just load the .3mf file into the sIicer and get to printing!
I don't know how well it will work with other slicers or other versions of PrusaSlicer.

Don't mind the odd shapes in the middle compartment on the tray in the preview! They are supposed to be negative volumes. If they aren't, just change their type to negative volume.

• Removed - Three file slots (from 6 slots to 3)
• Removed inner hole in the magnet holes to make printing easier (can easily be brought back)
• Changed - Width of the entire unit, now fits in a 1×4 Gridfinity grid instead of a 2×4 Gridfinity grid
