Small Printable Spool (Fits on MP Select Mini) by SouthTread

Last crawled date: 3 years, 5 months ago

I wanted to print a small spool for wrapping Makerbox filaments onto for printing, but all of the options I found were either too big for my little printer or took up at least 100g of filament to print. This spool prints in two halves that snap together after printing. it takes about 40g to print in about 3.5 hours and looks like it would fit double the length of filament that the 100g spool would hold.
I found it to be hard to wrap the Makerbox filament by hand (and I accidentally tangled the wood-fill while wrapping and snapped it halfway, oops!) so I'm probably just going to hold on to a few empty 1kg spools once my next few run out. I wanted to post this anyway in case anyone else would find it useful.
I realized after printing the first half that the hole was not only too small, but feeding the start of filament through it would make it hard to spin on the Monoprice Mini's stock spool holder. I'll make a version with a larger hole for people who don't care if the center is obstructed, and another version without the hole. I used tape to hold the start of the filament in place.
The image above is with a full 50g sample from Makerbox wrapped on.
EDIT: alexhop has discovered that this spool will hold just shy of a 200g roll from Push Plastic (about 195g)
