Modular scale model paint rack

I present to you my take on a modular rack for model paints.
It fits small vallejo, ammo etc 17 ml. bottles as well as Tamiya 10 and 23ml. jars and also square 40ml. Tamiya glues, washes etc. Most AK/AMMO/Vallejo washes, pigments etc. fit into Tamiya 10ml. shelves.
All you need to do is to print both side walls (sidev2 and sidev2 mirror stls) and then choose your shelves (top and bottom eg. vallejo+vallejo-bot).
Everything is pretty much friction fit, no glue required. If you want to wall mount this rack, you'll need to print wall.stl as well. It uses 2x M3 bolt+nut and 2x 5mm OD wall studs.
Each shelf is able to fit either 8x Vallejo 17ml. bottles, 4x Tamiya 23ml. jars, 4x Tamiya 40ml jars or 5x Tamiya 10ml. jars or whatever else fits there, this is the most flexible use shelf of them all.
