Twsbi Vac Mini rear cap remover tool

thingiverse

I created this tool in order to remove the rear cap of my Twsbi Vac Mini fountain pen. Some ink got into the threads making it very difficult to cleanup. In order to print this tool with FDM, I suggest laying it in the print-bed with the handle oriented vertically (see pictures), so that the side that goes to the piston filler axle, lays flat on the bed. This will ensure that layers will be oriented so that the prongs have maximum strength and best accuracy. I printed it with PLA, normal settings in Ultimaker Cura 2+: 0.4 print head, 0.15 layers and usual speeds and temperatures. Feel free to experiment :)
