Ratchet Strap Spool Keeper

thingiverse

A simple but effective ratchet strap spool I designed. The Ratchet strap spool operates on a similar principle as the standard ratchet handle. I used a TRON 608 ABEC 9 Bearing for the design. The skeleton side that is used to wind the strap up was just a little too small for the diameter of the bearing, so I used hot glue to secure it. It's functional and overall I am quite pleased with the end result. Pictured is a 1" wide 15 foot nylon ratchet strap. I don't think it's possible to squeeze in a 20 foot strap without scaling up the holder or reworking the part. The tolerance on the print was small enough that friction keeps the spools from unrolling by themselves. I've uploaded a new photo showing the first 2 printed hanging freely in the air by themselves. Here is a video of the first print:https://www.youtube.com/watch?v=FfiNqtwIhBw Instructions Printed with these modified values in slic3r Layer height: 0.3mm First Layer: 0.25mm Perimeters: 3 Solid Layers: 3 / 3 Fill Density: 30% Fill Pattern: Archimedeanchords (slow) Top / Bottom fill pattern: Archimedeanchortds (slow)
