This was one of my first designs and prints and it takes care that an open bottle can’t tumble down. As minimalistic as it is… since I use it, there was no case anymore, where paints or solutions were spilled over my working desk. I can even left a long brush inside the bottle – no problem, it will not turn over. That’s why I call it the “Bottle Butler”!

My design is made for Microscale bottles (I use it quite often for the fantastic decal softener, made by them) so inner diameter is 30mm. Sometimes I use nail vanish for my craftwork, so I made an inlet for these bottles (D=25mm) so I can use the same Bottle Butler for both kinds of bottles.

You have bottles of different diameter? No problem… just scale up/done the Bottle Butler in your slicer software accordingly. Most slicer programs even give you the possibility to scale X/Y with different factors, than Z-axis. ;-)

Have fun!

Update: Added a square version for 7/8" x 7/8"-Testors/Pactra-bottles. Hope it works.
