Description:
The SHORTCAT is a 18″ tall, 12″ wide Pyramid framed 3D printer.
X-travel: 155mm
Y-Travel: 170-190mm
Z-travel: 210-220mm
This machine is made by: mrkimrobotics.com
Design:
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.
Thin-profile x-assembly:
Y-Carriage v3.0:
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:
(1) board
(4) holes
(4) 3"-5/16" carriage bolts
(8) 608 bearings
(12) 5/16" washers
(16) 5/16" nuts
Belt Clamp:
(2) #6 x 1" wood screws
(2) M4 nuts for spacers
(2) M4 fender washers
Note:
The timing belt now faces outward so the smooth side rides on the pulley.
There are (3) 608 pulleys for the belt mounted on the threaded frame rods.
Y-Carriage v2.0:
Drafting film (surface layer)
(table layer)
(compliance layer)
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.
