As you can see, the hole in the bolt goes at an angle, so you can feed it in from the back at the top and it comes out at the bottom. It's a very clean solution and you can screw it on almost airtight.
I'm gonna print 2 more of these and fill out my box with 3 spools. Have fun and let me know if you print one!
I printed at 25% infill and it's REALLY strong (ABS). It's made for 1.75mm filament (tight fit! but smooth)
