Though it was my first choice for this project, the Australian 2 cent coin<\/a> has been withdrawn from circulation in 1992 and is rather difficult to get a hold of. \u00a0Next in line is the Australian 5 cent coin<\/a>, which apparently at certain times the metal value exceeds the face value. \u00a0The important attribute for this project is the weight of the coin, the 5 cent coin is almost half as light as the 2 cent, 2.83g vs 5.18g respectively. \u00a0What kind of project is this where the weight of the coin is important?!?<\/p>\n

Sometimes while trawling the \u00a0stupidities of some internet forums [or Youtube comments!!!], one is tempted to put their 2 cents worth into the discussion. \u00a0Though the temptation is strong, that usually means lowering yourself to posting in a stupid thread just to try in vain correct some idiots stupidity. \u00a0Thus the idea was born of giving someone your 2 cents [5 cents now due to aforementioned difficulties] worth in a different way…<\/p>\n

….. Everything above that was written months ago …..<\/p>\n

But now that I got my grubby hands on a PP3DP Up! 3D Printer<\/a>, I’ve decided to give the printer a test and try out a prototype print! \u00a0I had to modify the model from its original Shapeways<\/a> intended print style to one that suits the PP3DP Up printer. \u00a0Just to keep things simple for the first prototype print I also removed the rack and half pinion and the geared motor mounts (Did I mention this is meant to be motorized?)<\/p>\n

You will notice that the ‘plunger’ is printed twice. \u00a0With FDM 3D printing, the orientation of the print is very important to the strength of the model. \u00a0I am printing on ‘Fine’ and ‘0.2mm’ resolution on the Up! printer here, you’ll see the details in the next photo and video.<\/p>\n

And here is the obligatory test run video on Youtube… nope not in a bathtub…<\/p>\n

If it is not obvious, the next steps is to put a rack on the plunger, a half pinion attached to a geared motor to drive said rack to pull the plunger, and then put it on pan\/tilt servos then upload it all to thingiverse to share the fun \ud83d\ude42<\/p>\n

But as always, I’m very slow to finish projects… does anyone want to see this finished? \u00a0Post in comments for a bit of motivation \ud83d\ude1b<\/p>\n","protected":false},"excerpt":{"rendered":"
