DIY solar filter holder for Celestron 127 SLT

thingiverse

Solar filter holder for Celestron 127 SLT telescope. The "ring-127.stl" should be printed twice, between which the solar filter is sandwiched and fixed with double-sided tape (with the holes on the ring aligned). It can then be mounted to the "cap-hollow-127.stl" and locked by rotation, providing a safe setup for light filtering. Note: the cap is a tight fit for the scope, and the inner side could need to be sanded a bit if it cannot be mounted to the scope.
