I was running some LEGO® Technic™ projects with very young kids (under 3) and found out, that their fingers didn't yet work very well with inserting LEGO pins, especially in harder to reach places. So I've designed a tool that helps with pushing LEGO pins into places.

Turns out it also helps elder people or people with some handicaps resulting in lessened gripping strength - this way they can insert those LEGO pins with ease and enjoy building despite e.g. arthritis.

This is very easy print, very tolerant to layer thickness, the only thing is your printer shall be halfway properly calibrated in the XY dimensions, so that the pin has the right amount of friction in the tool hole.

Print Settings

Printer Brand:

Prusa

Printer:

i3 MK2.5

Resolution:

0.15 up to 0.35 work

Infill:

20% is enough

Filament: Generic PLA doesn't matter

Notes:

Print standing on the pin hole (as designed). Use a brim to help with standing straight. NO SUPPORTS or you will never get them out of that hole.

I provided a GCODE file for a Prusa printer for a 0.15 layer height and one for a 0.35 layer height, both for printing with PLA and 0.4mm nozzle. The 0.15 is a bit smoother, but functionally there's no difference.
