Unclogging the 3D20
Read the Dremel 3D20 manual and these instructions before repairing a jammed extruder in your Dremel 3D20. Failure to comply with the warnings and instructions may result in fire, equipment damage, property damage, or personal injury. Always unplug Dremel 3D20 from its power before performing any service procedures. Failure to do so may result in personal injury and equipment damage.

Repairs on Dremel 3D20-01 may require the use of special tools (pulling devices and bearing press). Authorized repair centers have trained repair technicians and equipment necessary to perform these repairs.
