New coin trap!

prusaprinters

<p>More people than I thought liked my coin trap design. I wanted to address a few people‘s concerns with the various sharp points which made it less than ideal for children…&nbsp;</p><p>It has had all it's dangerous looking corners filleted and chamfered to make them look nicer and print better. I would have done all fillets but they don't look good when printed horizontally to the build plate.</p><p>I want each version of the coin trap to be similar to the previous but unique in its own way. I thought of two pyramid coin traps put together and I started designing this one :)</p><p>As with the previous coin trap it is sized for a US quarter which is about 25mm (1inch) but it can be scaled to different sizes to make it fit other coins. the sphere in the center is 26mm in diameter.</p><p>This is a challenging model to print! I used no supports and I do not recommend you use supports as they will get wedged into all the holes. When pausing to insert the coin I noticed that the extruder lagged a little and didn't push enough filament through so it under extruded the first pillar it tried around the coin. The print succeeded however and I think that this could be remedied by moving the pause higher up. I posted a .gcode however if you want to take a try at it. I would love to see a make that fixes this problem.</p><p>&nbsp;</p>
