Printrbot Simple X-Axis Extender v2

thingiverse

This upgrade uses 400mm rods and a 12x6in aluminum plate to extend the build volume of the Printrbot Simple to ~140x290mm. The bolts attaching the metal plate to the upgrade are countersunk so they sit flush, increasing printing area to near full. Parts that it requires are listed below: 15x 20mm M3 Bolt 4x 25mm Countersink M3 Bolt 4x M3 Nuts GT2 Timing Belt 2 Zipties 4 Springs from Clicky Pens Instructions The 4 counter sink bolts are used for bed leveling in conjunction with the springs from the clicky pen. The final 20mm M3 bolt is used to trigger the X end stop. The rest is pretty self explanatory when looking at the pictures.
