Fly fishing reel

I've been working on making 3D-printable fishing reel from skratch for a while now and finally got it done. 

I will continue to work on this design to provide different options and visual appearances. 
 

Introducing my 3D-printable fly fishing reel, engineered for simplicity and performance. 

Designed to be easily assembled, this reel integrates seamlessly with a 608 ball bearing and utilizes standard hardware including threaded inserts and bolts.

Bill of materials, main dimensions and assembly instructions in better resolution are attached as PDF-file.

Key features:

• Efficient Design: The entire reel requires just 93 grams of filament, making it lightweight and economical to produce.
• User-Friendly Assembly: Designed with DIY enthusiasts in mind, the assembly process is straightforward, requiring only common tools and components.
• High Compatibility: The reel uses a 608 ball bearing, a standard part that's widely available, ensuring smooth operation and easy replacement.
• Durable and Reliable: Constructed with sturdy materials and standard hardware, this reel is built to withstand the rigors of fly fishing.

Options:

• As per revision 02 on June 8th 2024 - Reel base has right and left handed option. Seperate print profiles for both are created.
• As per revision 03 on June 13th 2024 - Introducing the 'Sleek Spiral' design – featuring elegant, concentric curves that enhance style with a modern twist. Fully backwards compatible with the original version. Files for the new design (Items 1-3) are uploaded as a seperate plate and raw STLs.

Hardware:

• 1 x 608 Ball Bearing
• 2 x CNS 4557 - M4 x 0.7 x 10 bolt or similar socket head bolt
• 2 x CNS 4355 - M 4 x 6 bolt or similar
• 1 x AS 1427 - M2 x 6 or similar countersunk M2 bolt
• 4 x M4 threaded inserts
• 1 x M2 threaded insert

@Update, Revision 02 | June 8th 2024

General revision description

As few of you have already mentioned in the comment section, I forgot to include items 8 and 9. These are now included in the print profiles. Original file included base meant for left-handed, I now added option for right-handed. 

Geometry updates

• Item 4 - Mounting hole diameter increased from 6 mm to 7.2 mm to provide more options for bolt selection.
• Item 7 -  Hole diameter increased from 5 mm to 5.5 mm for easier installation of M4 threaded inserts.
• Item 15 - BOM had a mistake M3 bolts instead of M4 bolts. Preferable bolts replaced with correct size different type and size. 

BOM

• Replaced Item 15 with correct sized bolts. M3 → M4

@Update, Revision 04 | August 28th 2025

General revision description

The print profile "P1S, P1P, X1 - Right Hand Base" has been updated.

"Support/object first layer gap" has been increased to 0,5 mm.
This change should make support removal and cleaning much easier. Users should now be able to lever a small screwdriver in between the center support and the main body. It's also possible to loosen supports from the top.
