Edited from Eric's description
This is designed for 1st ACs and other camera department members that use a Robocup and need a place to set a few items down.
Holds 1 sharpie, couple lumocolor pens and couple sharpies, most smartphones, Fatmax tape measure, misc tools, or even most laser measures in the phone compartment, now that it's wider
I made the phone holder wide enough to not only hold a phone, but also alternatively my Hilti PD40 laser measure. Now the maximum dimensions are 87.5mm x 33mm. If you don't need that, this is also nice for holding both your phone and wallet.
Slide up from the bottom of robocup to mount. It fits into the grooves of the cup.
Eric has a “Plus size version for those with large battery cases/pop sockets.” But this is a mega large version to fit a laser measure.
Eric's listing has f3d files to make your own. I made this in Tinkercad like an idiot before I learned Fusion.
Don't print this in PLA. Print in Petg or ABS. PETG worked fine for me.
Orientation top down, no supports needed necessarily but the phone compartment is now so wide that it might cause issues without supports. Otherwise no necessary
Use 5 walls for the first 30mm, then above that for the rest of the pen slots and phone compartment, you can add a modifier to use only 2 walls (2nd picture). That saves around 30-40g of filament.
EDIT: afterwards I learned that you can use a “height range modifier” (that's what it's called in bambu studio) to change from bottom to 30mm to use 5 walls, and global is 2 walls, or vice versa.
The author remixed this model.
I further modified tblischok's version of eugland's (Eric U.) original insert.
