Printrbot Jr. Bowden Extruder Mount

pinshape

Attach a zip-tie to an extruder or similar component directly to the Y-axis sandwich on a Printrbot Jr. This item was designed with Tinkercad and can be edited online at https://tinkercad.com/things/dF7mqg9BZ7X Print it (I successfully printed it using a 0.35mm nozzle at 0.35mm layer height with 0.15 rectilinear fill, but other settings should also work). Press the item firmly onto your Y-axis sandwich as shown in the image. If alignment is off, measure the differences and modify the model at Tinkercad if necessary. Secure the motor to the platform using two out of three slots that are most convenient for your specific extruder type with a zip-tie.
