Printrbot Plus Quick-Fit Upgrade v1/v2

thingiverse

Easily upgrade your Printrbot Plus to Richrap's quick fit system by just replacing the topplate of the original extruder mount. This enables you to still mount the original extruder without the old topplate or with the supplied adapter, the quick fit way. In the development of the extruder, I appreciated this solution as it allows easy switching back to a working extruded. Update v2 has integrated M3 threads for mounting extensions like fans or Z end stops and a stronger adapter plate for the original extruder. The parts are now easier to print separately, glued/melted together with acetone (works only with ABS). Instructions: 1. Print the needed parts. 2. For v2, glue/melt the house onto the topplate using acetone and fill up five M3 nuts with in acetone-dissolved ABS. 3. Dismount the original extruder and topplate, countersink the two holes. 4. Mount the latch to the topplate with bearings, screw, washers, and lock nut. 5. Attach the topplate to the Printrbot Plus using four 10mm screws and nuts. (Optional adapter: Countersink two holes in the adapter, glue/melt reinforcement with acetone, and mount the adapter plate to the extruder using two screws and nuts.) BOM includes a printed topplate (v2: topplate and house), latch by Richrap, four M4x10mm flat head screws, four M4 nuts, two bearings, one M4x30mm screw, two washers, one M4 lock nut, five M3 nuts (v2 only), optional adapter (v2: adapter and reinforcement), and two M4x16mm flat head screws with two nuts.
