Gridfinity nib-down fountain pen and marker holder

This gridfinity fountain pen holder was designed to accommodate the majority of my fountain pens in a nib-down configuration. Specifically, it accommodates a <14mm diameter, <4mm clip depth, and <9mm clip width pen. Do note that smaller diameter pens will allow for larger depth clips (A Platinum Preppy, at 12.75mm diameter and 5mm clip depth will fit fine)

Editing these values should be fairly simple to do in fusion 360; just edit the values in the sketch and it SHOULD work fine. Probably.

From my small collection, this works will with the Jinhao 599 (Lamy safari clone), the Pilot Explorer, the regular Sharpie marker, and the Platinum Preppy.

Smaller diameter pens and pencils, as shown in the pictures, don't seem to work as well.

Larger pens, such as the Noodler's Ahab, cannot be placed nib-down.

Brazillian TUSH Holder (a gridfinity spool holder).stl

As a woman of a certain age, I realized that my [TUSH](https://www.thingiverse.com/thing:2047554) needs a little extra support. I tried supporting my TUSH with [conventional methods](https://www.thingiverse.com/thing:4645143/files), but I noticed that throughout the day my TUSH would make quiet "clapping" noises as it wobbled back and forth; it is quite embarrassing. With the help of Mr. Freedman's [gridfinity](https://www.youtube.com/watch?v=ra_9zU-mnl8) system I designed something that could accommodate my needs. Since this is only the first version, I decided not to name this "infinity tush holder" to reflect its full integration with the gridfinity system. However, it does seem to work quite well, so I chose a number which is close to infinity: a brazillian.

The "H" shape of this part is to facilitate nesting a 1x1 gridfinity bowden bulkhead, the design of which is to be released later.

Parts needed:
2x m3 16mm screws (optional - works fine without)
1x [completed build of the adjustable TUSH stand](https://www.thingiverse.com/thing:4645143/files) (requires 1x 608 bearing)
1x [completed build of the TUSH](https://www.thingiverse.com/thing:2047554) (requires 4x 608 bearings)
1x [gridfinity grid](https://www.youtube.com/watch?v=ra_9zU-mnl8) (3x4 minimum size) (optional- works fine without... but why would you? I guess you could slice the bottom bit off the STL if you don't want to use gridfinity)

NOTE: The f3d file is slightly buggy due to poor decisions. A lot of work was done in 3d mode just hacking off bits from Zack's template, and for some reason a few planes don't align precisely because of an odd rounding error.

The STL prints fine. Any reasonable amount of infill will work.
