Recently, I planted a succulent plant in a 3D printed Low Poly Bulbasaur Planter. The print was done in pla on a UP! mini, I printed it a while ago but finally spur of the moment bought a little succulent from Walmart and planted it. Next time I would like to buy the plant from a local nursery but it seems to be growing well. The model (thing:381599) I printed was by Hitsman on Thingiverse.
I designed this to attach a iPad Air to my Manfrotto tripod using the quick release. You can download the STL files here: https://www.youmagine.com/designs/adjustable-ipad-air-manfrotto-tripod-q... or http://repables.com/r/489 . It has four parts total and three printed parts (two of the printed parts are exact copies). It can hold the iPad in portrait or landscape by sliding the corners. The quick mount should be static in the center of the aluminum bar so use glue if the fit is not tight. The corners should be adjustable with friction.
