3D printed dew shield project

[hawksquawks]

Evening all thought id share my project with you so just over a week ago I purchased a 120mm telescope without a dew shield so I decided to make one myself.

 

First off I made a simple cylinder measured to the correct size for my telescope using 123d design took less than 2 minutes to complete 

 

Here it is loaded into cura nothing amazing LOL

 

 

 

After finishing the print that took just over 7 hours even with a 1.0 nozzle at 0.5 layer high I started to clean up the fitting so see if it fitted the scope, no photo but it fitted fine. you can see how ruff the layers are but this is ideal to bond resin to

 

 

The photo below shows the inside freshly coated with resin 

 

 

After the resin application I started sanding this process has been repeated twice to get the pits out of the tube, need to do a third run on this tomorrow

 

 

 

as for the outside of the tube I fiber glassed it pic below shows the tube just after application as you can see it requires allot of sanding.

 

  

 

After around an hour of sanding and allot of dust (wear a mask!) this is the result starting to look smooth but still pitted.

 

This image shows the second application of resin to fill the pits, at this point I have decided to stop tonight but i will sand smooth tomorrow in ready for painting 

 

 

With the dew shield almost finished, it's time to consider the dew cap. already designed in 123d just need to print it

 

 

Ill update when this project is finished.
