A 2x1 organizer tool bin compatible with the amazing (although unfinished...) Gridfinity Refined system by @grizzie17.
Features:
One slot for a standard X-Acto knife in a stable fashion, fully protecting the blade and not making the bin top-heavy - something that aggravated with some other popular designs).
One slot for an X-Acto No. 11 Knife Blade Dispenser (the 15 blade version). Pro-Tip: those dispensers are actually refillable. The dispenser serves as a counterweight to the X-Acto knife.
No Gridfinity Refined center screw thread - reduces print time
Magnet slots which accept typical 6x2 mm magnets. The original slots in Gridfinity Refined had a floor that was too thin and would rip out when magnets were inserted. This was addressed in this model.
