Additive Manufacturing
When I first started experimenting with 3D printing, it was a hobby born out of necessity. Limited by commercially available parts and custom adapters, I quickly realized that 3D printing could fill the gap between what was available and what was needed in astrophotography.
From small adapters to complete mounting solutions, I’ve used 3D printing to solve practical challenges in my observatory setup. Below are some of my favorite printed designs, which can all be made on a typical desktop FDM printer.
Dust Cap Replacement
Lost or cracked a dust cap? With a 3D printer, it’s easy to create durable replacements that fit snugly and stay secure. This custom design replaces flimsy OEM parts and can be printed in PLA or PETG for excellent strength and temperature resistance.
Guide Scope Counterweight Solution
Perfect balance is critical for guiding accuracy. To counter the offset weight of my guide scope, I designed a simple 3D printed counterweight bracket. This setup reduces mount strain and allows me to fine-tune the center of gravity for optimal tracking performance.
ASIAir Cable Management Caddy
Managing cables is one of the biggest challenges in imaging sessions. This caddy keeps my ASIAir mounted neatly and organizes cables to avoid tangling or snagging during long exposures. Each version is customized for different telescope setups.
Controller Bracket Mount
The original hand controller mount for my telescope wasn’t sturdy enough, so I printed a stronger version that attaches directly to the tripod leg. It’s rigid, reliable, and keeps the controller easily accessible without loose cords.
Universal Adapter for Focusers
One of the biggest frustrations in astronomy is the lack of standardization between focusers and adapters. This universal adapter bridges incompatible threads and diameters, providing a stable, secure connection for filters and accessories.
ZWO EAF Focuser Redesign
This redesigned ZWO EAF mount replaces the original metal bracket with a fully 3D printed alternative. It offers improved rigidity, perfect alignment, and a sleek fit to the telescope’s focuser. I printed it using high-strength PETG for durability and heat resistance.
