3x Alcohol Ink Holder Gridfinity 1x1

This 1x1 gridfinity block holds 3 alcohol ink bottles plus stirrer sticks. The bottle diameter is approximately 20mm.  I was going to release a 2x2 block and larger, but I could only squeeze in one extra bottle spot for the 2x2 (13 spaces instead of 12 that the 4 1x1 blocks would hold), so scrapped that and just decided to print multiple of this 1x1 to fit my needs. 

Made with OnShape, modify it here.
