Filter drawer store??

[PeterW]

Picked up an Altair filter drawer system to enable me to hot swap filters when observing. Now what to do with the ones I am not using…?? So I made me a box to hold 2 back to back. Added a few metal screws to give the included magnets something to hold them (not hugely strongly) in place. Worked on the first print too!

Lovely it is! But wondering why didn't you print the entire replica of that Altair and save some dough for a couple more NBs ? 🤔 Should be totally adequate for visual e.g. in CF PLA and you can design it way slimmer than that Altair assembly.

Cos I am using it with NV, so longpass, narrow hydrogen and  spare… good thought for if I feel the need for another filter drawer. One issue with 3DP is fine threads, tend to be a “only thread on once” affair. I could also use stronger magnets too! I wouldn’t trust a fully printed housing due to the thread issue. It could be a bit thinner, but I can reach focus with what I need to. I also printed a thin spacer so the t-thread adapter on one side doesn’t screw in so far it fouls the filter tray.
