Connection rails stolen from an older project of mine. They're known to work when printed in resin. Contact me with results of FDM (remember to print in highest accuracy possible with decent filament) and I might make a revision just for that if it doesn't work.
The 25mm bottle holes are 0.2mm wider to accommodate for errors. The 35mm ones are not as the bottles seem to be roughly 0.5mm smaller to begin with.
Both versions are stackable with each other.
Remember to stack side to side before front to back as desired (I think; tell me if I got it wrong).
More content such as vertical stackers possibly coming in the future if these do well.
Painted bottles in the pictures are just for reference. It should work with all Vallejo, AK, etc (25mm) and Tamiya, etc (35mm).
