I designed these parts while testing the SVBONY MK127 for astrophotography and visual use.

The goal was simple: make a few practical accessories for the MK127 that are usually annoying or expensive to buy separately. In the review video, I talked about how common telescope accessories can add up fast — dew shields, focus motor brackets, adapters, and all the little parts that somehow cost more than expected.

So these files are free.

Use them, modify them, improve them, and let me know how they work for you.

What’s included

MK127 Dew Shield

A simple 3D printed dew shield designed to fit the SVBONY MK127.

Use case:

• Helps reduce dew buildup on the front corrector

• Helps block stray light

• Useful for imaging and visual observing

• Lightweight and easy to print

MK127 Focus Motor Bracket

A 3D printed bracket designed to help mount a focus motor to the MK127.

Use case:

• Helpful for astrophotography

• Makes electronic focusing easier

• Designed around the MK127 focuser layout

• Built for my own setup and shared for others to test

Printing notes

These parts were designed for practical field use, not display-case perfection.

Suggested print settings:

• Material: PETG preferred, PLA acceptable for mild conditions

• Layer height: 0.2mm

• Walls: 3 or more

• Infill: 20–40%

• Color: black or dark material recommended for light control

• Test fit before final assembly

• Do not force parts onto the telescope

If you live somewhere hot or leave gear in a car, PETG is a better choice than PLA.

Hardware and belts

Some setups may need extra hardware or belts depending on your focus motor and exact configuration.

Important notes

These are community files, not official SVBONY accessories.

They worked on my MK127, but 3D printers, materials, tolerances, and telescope batches can vary. Test fit everything carefully before using it in the field.

Use at your own risk. Do not overtighten anything. Do not put stress on the focuser, corrector, or optical tube.

Don’t have a 3D printer?

I am not trying to turn this into a parts business, but if you do not have a printer, you can email me and I may be able to print a set for the cost of materials plus shipping.

Approximate material cost:

• Focus bracket: about $9

• Dew shield: about $10

• Shipping: usually about the same cost as the part, depending on location

In the video, I test the MK127 on M51, talk through collimation, compare it to the C5 and C6, and explain why I think this scope makes sense as a compact budget galaxy hunter.
