tinytim ultimaker feeder
thingiverse
Designed a custom feeder for my Ultimaker using only existing materials over the weekend. The upgrade features a rollerblade bearing, pressing fibre against the hobbed bolt with spring-loaded end block. Manually placed vertices; prints well so far. Tested for weeks to improve further, if time allows. Rescaled parts for accurate 1:1 printing. Uses stock Ultimaker feeder components, rollerblade bearing, two extra 3x30mm screws, two small springs, and an 8mm bolt/tubing. Post-processing needed on end-stop; file off overhangs for proper hook attachment. Easy assembly.
