Detachable bic pen holder with adaptative pressure for plotting with Geeetech A20M

thingiverse

The pen holder detaches for Bic recharging, perfect for your Geeetech A20m. The spring prevents issues if you fail to set the Z offset accurately and allows a degree of freedom in bed leveling. It also enables quick detachment and attachment of the pen multiple times without printer manipulation each time. Having multiple pen holders with different colors is fine too, although it's easy to have just one and change the Bic recharge frequently. New (28/05/2020)... A refined version has been uploaded not to stand out as much, now the recharge is hidden inside and allows self-leveling of the bed.
