This is an updated case for the Little Garden Spectrometer by Lao Kang found on AliExpress. The model is one inspired by Project 326's YouTube video on upgrading the spectrometer, I reached out to try and get them to send me their model, but with no response, I just went ahead and made my own based on what I saw in the YouTube video. 

Mine the mounts use the same screws from the original case, be careful they sometimes snap if screwed in to hard.

The case is put together by 4 m3 heated inserts screwed in from the bottom with m3 buttonhead screws

The front of the case uses 4 holes that m2.5 screws go right into nicely to secure the sma905 adapter
