Karas Kustoms is proud to announce our latest project, a custom machined pen, the RETRAKT. We have chosen the name “RETRAKT” because this new pen is a “click” style pen that uses a near-silent mechanism to expose and retract the tip of the refill in use. The RETRAKT features a German-made, all metal, knock mechanism, our signature heavy duty stainless clip, and will come in 3 different materials. In addition to aluminum and brass, we are introducing a version in copper, a first for Karas Kustoms. The aluminum version will be anodized and the copper and brass versions will be hand-finished and left raw. As always, everything from design to manufacturing is all done by us in our shop. Here are some nice photos for you to ogle.

Makerbot Replicator 2 Extruder Upgrade

We have manufactured a small batch of extruder upgrades that are work with the Makerbot Replicator 2 3D printer. They are made from anodized (red!) 6061 aluminum and have a brass pivot pin. They come with the bearing pre-installed, a 3x8mm countersunk screw, and a spring. You just need to reuse one of the long screws that came with your original plunger with the brass pivot pin. This design is derived from whpthomas's design posted on Thingaverse. We asked his permission and he told us to go for it, so we did! This upgrade kit will NOT work with the 2X.
