Parts List:

• 5x M3x4x5 heat set inserts
• 1x 608 bearing
• 4x M3x10+ SHCS
• 1x M3x14-18 SHCS

Assembly is fairly straightforward. All of the heat set inserts are designed to be inserted from the bottom (i.e. they are “pulled through” when screwed).

Clamps work for 10, 12, and 14mm diameter rods. Because it clamps there's a fair amount of wiggle room, but the inserts are 10 and 12 mm respectively, with the base clamp being 14mm.

Designed to work with Piscifun spools or the spool I designed here: https://makerworld.com/en/models/518843
