Description
Back in the late 1970s and early 1980s, My grandfather carried a small flexible plastic pouch in his pocket to hold his change to keep it from rattling around. I was experimenting with TPU the other day (and still not good at using it) when I printed a wallet to see what you could do with it. The Wallet printed, well, ok. It showed me what can be done with flexible filament. So I did a search for a coin pouch like this and found nothing like I remembered. Off to Designspark to make one. I sat on the PC for 30 or so minutes and designed one and put minimal support on it. I ran it through my trusty old Anet A8 and it printed, not well, but it was successful. The problem with it was that it wobbled more and more as the layers went up and the quality got worse and worse.. Next morning I hopped back on the PC in Designspark and added supports. This printed MUCH better, but still has issues. I am a function over form printer and I have a tendency to print FAST and DIRTY with .3 layers. I did slow it down to 35mm per second to accommodate TPU printing but it is far from perfect. This is on my skill as a TPU printer, not the model. If you have a well tuned printer set up for printing TPU it should work out great for you, especially if you slow it down and set the layers to .15 or lower. Enjoy!

Tronxy TPUWhite
Notes:
I print on glass, so a good layer of aquanet (Hairspray) was applied. The bed temp was 50C the first layer was printed at 215C and all others printed at 190C. I set the printing speed to 35mm per second (I have direct drive extruder) and I had Z hop turned on to avoid wobbling.
These are my settings.. You can try them if you like.. they are far from perfect..Your Mileage May Vary.
After you print this and pry it off the bed, take some form of cutting device (I used side cutters) and clip off the support. Deposit the support in your choice of waste receptacle. You can clean up the print with some effort (TPU sucks for cleanup). Then you squeeze the pouch by the pointy ends and it will open. Place coins in the pouch and release the pressure and it will close. Place it in your pocket and stop fiddling around in there trying to find coins,
Have Fun!
I designed this in Designspark Mechanical (my favorite design software, AND IT IS FREE!). I created an oval pulled it into a cup, rounded out the sides and the inside, then copied it and rotated it 180 degrees, brought the 2 together and joined them. I then cut a slot in it and made 2 holes on the pointy ends. I then added supports and printed. kinda quick and dirty but it works...
