Replacement Solidoodle 3 belt idler pulley holder

thingiverse

This is an upgrade for idler pulley holders that come pre-installed on a Solidoodle 3. I'm unsure if this design will work with other versions, as my experience is limited to the 3 model. These holders are designed for use with 5mm rods, approximately 40mm long. Fortunately, you can purchase a pack of ten from Amazon for around $7. Replacing the standard M5 bolts that come with it with these holders is a significant improvement if you plan to switch to GT2 belts like I did. To install, simply mirror the part and attach it using a standard socket head M3 screw. The original screws are no longer required, as they only served to hold the old holders in place. Be cautious when removing the old holders, as they are secured with locktight and may be difficult to extract without damaging the surrounding area. Print this design on your build platform so that it forms a U shape when viewed from above.
