This is a bracket for installing a Nikon Coolpix P900 on the DOB Virtuoso by Sky-watcher (pretty sure other camera will work).
The original bracket was too flexible and also too short for the weight of the P900.
This bracket is sturdy, I took a photo of the moon at full zoom with the P900 with no problem (see)
I re-used the bolt of the original bracket to mount the camera on the DOB.
Designed with DesignSpark Mechanical.
no raft
no support, printed flat on bed.
25% honeycomb infill, most "solid" infill.
resolution 0.30mm layer high, good enough.
8h of printing with PLA on my Printrbot Play (now I have a MK3S)
