Wanted a stand for my Scentbird Vial holders that i could leave out and was aesthetically appealing. It was important to me to keep the holders out but also to avoid direct sunlight as that can affect the cologne/perfume and cause it to turn rancid.
This one is designed with 9 holders, staggered so the names show through the gaps in between the cases. The original case and the cases I printed from https://makerworld.com/en/models/153006?from=search#profileId-167168 both fit fine. the fit is slightly loose by design, I didn't want the cases to get caught and tip the rest of the stand over. Finally there's a cavity I placed in the bottom to conserve plastic. I find this also makes it less likely to warp with more difficult materials (ABS, ASA, Petg Etc).
Printed mine in CF but the settings should work for regular PLA also.
