About this model

02/01/2017 - Updated design, two rollers widths available and you will need four 608 skateboard bearings. The side supports have a built-in filament guides as well. There is a notch built into the rollers that will prevent the bearings from being pushed in too far. This thing works like a charm, it has been shared on the Prusa i3 Facebook group and downloaded and printed countless of times. Let me know what you thing if you print and use it! You will want to print the nuts and bolts with a high infill (at least 50% to 75%) I have been using these bolts for a year without issues. And 13% to 20% for the rollers and supports will be fine. Print using ABS! 11/28/2016 - Updated design, clears extruder. This is a spool holder that allows you to quickly remove and place a new spook on the printer…
