The SHORTCAT is a 18″ tall, 12″ wide Pyramid framed 3D printer.
This machine is made by: mrkimrobotics.com
The SHORTCAT applies TALLCAT style design in a more compact form factor.
By bending the supports into a pyramid shape, a symmetrical base is possible that uses no frame spacers. This significantly extends the x-axis travel and allows a 8″ wide table to exit the front and back of the machine on the y-axis. A thin-profile 360 bearing allows for clearance from the shorter pyramid.
Version 3.0 has been reduced to a single part.
The v3 y-carriage integrates an adjustable build platform and bearing assembly in a single layer.
This design uses:
(4) 3"-5/16" carriage bolts
(8) 608 bearings
(12) 5/16" washers
(16) 5/16" nuts
(2) #6 x 1" wood screws
(2) M4 nuts for spacers
(2) M4 fender washers
Notes: To allow the belt to reach the higher mount point of the build platform, (3) 608 pulleys are mounted on the threaded frame rods. The timing belt faces outward so the smooth side rides on the pulleys.

Scoop Extruder v2.5.3:
Version 2.5.3 experiments with a shorter 58mm body to make the central bore easier to drill.
It is slightly more compact and has a shorter distance after the drive gear.
The Shortcat was designed for easy access to 36" rod lengths that are cut in half to 18".
