I attempted to do the snap-fit in a series of computer aided design software like Inkscape, Illustrator, GIMP, Grasshopper and found it to be quite difficult to what I’m used to. So the frustration with grasshopper made me crack and go for Rhinoseros 5. I do know this software quite well and find it incredibly easy to get things done and therefore makes it possible for me to achieve what I had planned to do which was to make two different types of snap-fit models and a project. I will however go back to Grasshopper and redo the snap-fit project.

images

drawing lines (line tool) in rino to the desired dimenions (it helps to phisically draw it out before using CAD)

highlighting the lines and mirroring the lines (type mirror in the command line nad follow the instructions)

the dimensions i used

here i rotated the lines four times (see tutorial further bellow)

in correl draw i imported the DXF file to scale and made a small cutting list (i made one master "key" with different dimensions for the snap-fit test)

i used a Epilog 36ext with a 60watt tube (bellow are the settings)

cutting 3mm acrilic

finished

it is important to think about your cutting list to minimize waste

my test (findings were that fitting no 2 and 3 were the strongest and most snug fit)

for my table in my final project i would like to achieve a different kind of snap-fit model made from 3D printed ABS and wood so I used this chance to familiarize myself with this model

it did not work because my dimensions were completely wrong

here I think is why- but if you continue with this page you will soo see why

new model

if you compare the new model with the old one (i found that this was ideal as the teeth of the snap were to thin and also to long, i found that it is really important to make the teeth about 0.3 bigger than the slot)

my different types (i cut them out of the same acrilic sheet with the same cut settings)

small snapfit projects

my problem

Laser cut from 3mm wood and clear acrylic (acrilic used was 5mm and 3 mm)

downloaded a texture from the internet and traced it in Inkscape to be cut from vinyl

our vinyl cutter

once the vinyl was cut, i used a white board marker and colored in the lines to see them better when working

here you can see the cut lines

then i carefullf stuch it on the sheet of already laser cut wood (i did need sum help with alignment)

the tedious work of peeling

finally done

i did not like the look of it so i decided to spraypaint the wood white

my snap-fit joint (here you can see that I made a master snap-fit that holds 4 pieces of material: 1 piece of 3mm wood, 2 pieces of 5mm acrilic and 1 3mm acrilic piece)

adding all the master joints

done

my problem solved

pencils and pens fit ferfectly

angle of the copix is also good

otherIssues I had and am still having

I need to do these snap-fit models in Grasshopper as it will get my mind into the world of coding. I plan to use this Tutorial:

If anyone has better tutorials I can follow please be so kind to share.
