777 Big Money Project

The RepRap motto is "wealth without money" - for this assignment you are to create wealth by making an open source design that has value to you. It must be 3D printable on your MOST Delta and cost less than a commercial equivalent (if such a thing exists).

Assignment[edit | edit source]

Design something of "high value" that you can 3D print on your MOST Delta
Make sure someone else has not already done it - search http://www.yeggi.com/ and http://web.archive.org/web/20191229012720/http://www.yobi3d.com/
Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
Upload your design under an OS license to https://www.myminifactory.com/ or https://libre3d.com/ - include: Source files, STLs, a picture, and a brief description including costs and $ savings.
Add picture, link to your MyMiniFactory or Libre3D page with name, commercial equivalent link+cost, and economic savings to table below (see example).
Print component and bring to class (online students - post a link to a short Youtube video)

2019[edit | edit source]

Free Design/Link to YouMagine	Commercial equivalent link/Cost US$	Approximate Savings in US$
Parametric Dice Box	Dice boxes vary in price by a large margin. The printed box was designed after a standard box [1] that costs $9.99. The printed box costs only $0.92 to print, having a saving percentile of 90.8%.
Ice Fishing Drink Holder	No commercial equivalent (perhaps a high quality thermos for $48)	This ice fishing drink holder features telescoping cylinders that immerse drinks within water through a hole in the ice, keeping them cold but preventing them from freezing while ice fishing. The top of the holder can be held against the ice via a weight, screws, or bolts. Cost: $12.12, Cost savings: $35.88 (versus the thermos). I have been offered $30 for this device, or a profit of $17.88 per device.
Seal Puller	Motion Pro Seal Puller $45.99	Printed pieces cost: $1.32, Cost savings: $44.67. This cost is for one handle and 3 different sized heads. Many different size and shape heads could be printed for this handle for different applications. A future project could make the heads fully parametric.
Open Source Camera Slider	Motorized Camera Slider $400.00 higher end camera slider $1000.00	Total Cost: ~$60.00, Cost savings: $340.00. The cost savings for this is huge compared to buying a cheap one on Amazon. There are other versions of sliders that cost well over $1000 on there as well. Here is the link to my page to talk more about the slider Open Source Camera Slider.
Cactus Taco Holder	Value: $8.49 for 4	This object was designed to prop up your hard or soft shell taco while making or serving. The fun cactus shape provides interest and whimsy. A similar taco holder can be bought for about $9 for a pack of 4 on amazon, but this version can be printed for around $0.25 worth of filament for a cost savings of about 89%. youtube link
Switch Stand	Official Switch Stand	This stand, used to support a Nintendo Switch such that the USB-C charging port is easily accessible, would cost around $1.82 in plastic to print, while commercial equivalents cost $13 or more, saving 86% of the cost.
Parametric Sprue	$15 10mm Sprue Form	This parometric sprue allows for users to print a sprue in usage with match plate casting. A single sprue, on average, costs around $15, but this print will cost only around $0.16. This is a cost savings of 94%! YouTube Link - Parometric Sprue
Parametric Metric Allen Wrench	$5.28 6mm Allen Wrench Key	Even printing at 85% infill, it takes less than an hour and costs less than $0.20. A single replacement could be around $5.00 and require you to run to a store or order online. A complete set can be around $15. This would work great in small torque applications and would be a 96% cost savings if small torque is all you need, but the biggest savings is the time. YouTube Link - Parametric Metric Allen Wrench
Dual Flash Camera Mount	$135.99 Camera Flash Mount	This flash mount allows the user to mount two DSLR camera flashes to the 1/4-20 thread screws found on most cameras.

Coffee Grinder Conversion Kit	[2], $139 Amazon Best Selling Electric Burr Coffee Grinder	Any planetary motor (the best being 100 RPM) with power supply will work. The printed components only takes 76g of filament to print. My cost of filament was $1.52, so $137.50 savings (99%).

PMAG Loader	[12], $26.95	Total cost is ~85 cents, with ~58 cents of plastic being used at the 30% infill I printed at, I had a clevis pin laying around but am assuming a 27 cent cost for a clevis pin if sourced from McMaster Carr as a worst case scenario, for a total savings of ~$26.10 over the closest commercial equivalent.

Dominion base card compact holder	[13], $19.99 full price, $12.99 on sale	The total cost for the two pieces is around $1.94 for 97g of filament.

Nordic ski binding jig (self-clamping)	[14], Not sold commercially, but you can find one used for $45-60 if you're lucky.	Expect the print to cost $2.00 at 20% infill. That gives a cost savings of 96% over buying an old used jig, and you save the time of hunting it down on random buy/sell pages. Using a jig to mount your bindings is extremely helpful for proper hole placement. Without the use of a jig, it takes much longer to correctly place the mounting holes. The jig sets perfect alignment every time and greatly speeds up the process. There is currently one OS binding jig, and it does not have a clamping mechanism and does not align itself to the ski. See here. The new design both clamps and aligns. To properly use, print the base plate (two separate pieces that connect) then print two clamps and connect them to the base plate's extruded tabs. See the myminifactory link for more details.
