30-JAN-2018: NEW IMPROVED model https://www.thingiverse.com/thing:2778015
Details, links for electronic components & firmware downloads are at http://bigcooter.com/?p=1584!
28-DEC-2017: ADDED Toranado 120mm Fan Grill STL file, compliments the Toranado Extruder https://www.thingiverse.com/thing:1246951
20-JAN-2016: UPDATE - added sidecover with 2 terminal banana 12V Aux Power Outlet.
Build a low cost cutomizable 3D Printer Power Supply & Electronics enclosure. This is a modular design which can be configured multiple ways to utilize the plentifully low cost (<$30) 360watt power supplies used on many RepRap 3D printers. The standard 40mm high speed noisy fan has been replaced by a quiet large 120mm fan. Optionally, additional boards can be encased in this enclosure, such as: Arduino / Ramps boards, Raspberry Pi board/camera, etc.... The idea is to pick and choose the components to print, then build a customized electronics unit for a 3D printer ... with only minimal remixing and/or making of specialized board brackets. The Raspberry Pi module, enables the use of OctoPi, a fantastic OpenSource 3D printer interface with remote access and camera integration.
NOTE: Reference STL files have been included for all the purchased components, and for the BigCooter Raspberry OctoPi (in My Things at http://www.thingiverse.com/thing:713389 )
Design description will be as follows:
Make from universal Power Supply (12 or 24V, 360W)
120mm cooling fan - low noise ... LED lights look great!
modular design - versatile
board mounts for Arduino / Ramps & Rasp Pi - camera
option for mounting 4-Channel 10A Relay board
option for mounting 1-Channel 30A high current relay
Additional modules are coming, and I encourage others to develop their own compatible modules to share (when doing so, please follow the design standards below).
Currently available modules and components:
USB 12V power (for Raspberry Pi and other applications)
Raspberry Pi with camera
7" LCD display
120mm silent cooling fan
RAMPS 1.4 / Arduino
120V cord outlet / on-off switch
30amp heat-bed relay (recommended for RepRap machines w/RAMPS 1.4, prevents over-heating failures / fires, OMG!!!)
Base Cooling Vent / wire router
Oversize swivel base cooling vent with adjustable wire routing
Raspberry Pi Oversize base module
- in development - oversize modules are for use at base of unit, they provide added stability and larger electronics packaging
Suggestions for New Modules (link to here if you develop any):
Large base, for more stability
Graphical LCD display
Mount for BigCooter 7" LCD Display (see http://www.thingiverse.com/thing:676916 )
The blue/black pair of units in attached photos run a large 3D printer. One unit contains Ramps1.4/Arduino and the other unit contains a 4-channel relay board for running a large headbed with 4 heating zones (4 standard size heatbeds). Both units have USB outlets for powering devices and one has a Raspberry OctoPi which uses My Thing 7" LCD display shown in the photos. This demonstrates the versatility of this Enclosure, it can be configured multiple ways! .. resulting in a clean, low noise, professional appearing system.
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/aEgCTYQNRkx
PLA - black parts
ABS - colored parts
All plastic 3D printed parts have been designed to fit on most standard size print beds. The fully assembled unit approximately 12" tall x 5" wide x 4" deep.
All screws are M3 button head, with no captive nuts (thread PLA plastic using M3 tap, or "self-tap" the screw into the hole). Holes in plastic parts are intentionally undersized to improve hole quality and
size accuracy, resize holes with drill (30 to 3.3mm diameter drill for through holes, and 2.4 to 2.6mm diameter drill for M3 tap).
The included Picatinny 20mm Rails are designed to fasten to 3 sides of the 360W power supply case. This rail is the BigCooter standard mounting system, a widely used, versatile, strong system based on the original MIL spec ... almost anything you can imagine, can be mounted securely on this rail system.
