12-11-2023 - Added size 5,6 and 8

Ergonomic Allen key handles for multiple common allen key sizes used for 3d printers. More sizes will be added with time.

Every size has it printed on both the bottom and top to easely find the right size.

You can print all of the handles in one color like i did but print the keylock and cap in different sizes to distinguish them from one another.

I printed all of mine on a bambulabs p1p and a flsun v400 with pla from elegoo, filalab and addnorth. I have tested these to the best i could when working on both my flsun v400 and bambulabs p1p and have not had any failures with this version.

There is quite tight tolerances for the allen key to get as little play as possible so it may differ from printer to printer, hole compensation might have to be used if your printers tolerance isnt up to par or if your first layer is a bit too close to the bed. Silk filament does often have bad layer adhesion and could cause very weak prints so for handles that will be used with high forces I would recommend normal pla or slow petg without cooling for a very strong handle.

My recommendation for printing:

print the cap and keylock with the text down and print the handle with the top faced down for a 0 support print. If the handle is going to be used with very high force I would recommend 5 or more walls.

0.2mm layer height

0.42mm line width

no supports

25% infill and / or 3 or more walls

A big thank you to everyone that downloads and it would make my day if you upload your make! :D
