I did not want to use glue for the carbon fiber tubes, in order to dismantled for maintenance (dusting) of the main mirror, I have added this rawl plug system to keep the tubes together tight. Also I incorporate feet so when you put the scope vertically you do not affect the primary mirror adjusting nuts.
For those that will not use the fan, I added a TPU Dust Cover to minimize the dust entering in the scope.
Hardware : 8 pcs 5mm X 65mm screws with nuts
