This is a customizer to create a paddle sized exactly on your hand dimension.
You can configure it for your hand with open or closed fingers and you can change the shape of the paddle acting on CTW0 control points.
You can make it as a uniform thickness or you can have the hand area embossed, the reason of the hand embossing is mainly to reinforce a bit the center part if you print it thin.
There are some measures you should take of your hand, just put your hand on a paper sheet and draw the contour, with your hand roughly in the position you assume while swimming.
Select Edit_mode=3 and you can see the position of the various points. What you should measure are P1,P2,P3,P4,P5 and V1,V2,V3,V4,V5. Done that, just insert them in the customizer or in the file itself and see the result. From here, you have to adjust the control points CT01 to CT05 to shape the finger (the curve should touch the points T1 etc.)
Then you just select the thickness of the paddle. If you print it with flexible filament, you can make the webbed part very thin and have your hand pretty much free to move like for grabbing the ladder to exit the pool, but you should not make the webbing wider than the hand otherwise it will bend (should be something like 4th example).
For strapping, you can size and place up to 8 openings. Just put X and Y size to 0 for the ones you don't want to use.
On my ones I made 1x1mm openings and used flexible filament as strap but you can size the cuts to pass a velcro strap or flat strings.
The paddles I made are 2mm thick for the hand and 1mm for the pad area and I would make the pad a bit thicker next time, about 1.5 or 2mm.
I created these links where you can find all common filaments and spare parts at the best prices. These are just links to selected eBay and Aliexpress items, where I normally buy spare parts and materials for my printer, prices are excellent and products are good. If you buy something from here you will support me a little bit to make these projects.
