Hang your head in shame. The surface finish on that part your 3D printer coughed out over two to five hours could be used to remove the coarse back hair off a grandpaw yak. We’re currently doomed to the hype of hi-res 3d prints but still getting jagged edges and snagly bits gumming up our impressionable, early adopting minds. Fortunately, when it comes to such circumstances, there are people who have been there, tried 50 different things to improve it until one thing works. Makeraser is the one thing that works.

Makeraser is a small, hand-held tool that allows you to smooth the surface finish of your 3D print. It does it all quickly and easily by using a small amount of acetone delivered through a contrl-flow felt-tip. However (warning!) the Makeraser is much more than a print smoothing pen. It’s a multi-tool for the hobbyist, inventor, designer that needs a few tools that don’t come stock with your average 3D printer.

All together the Makeraser has four parts:

  • Flexible HDPE Controlled-flow Felt-tip Bottle
  • Wool Felt Nib + Washers
  • Marble inside Bottle to keep ABS + Acetone Mixture homogenous
  • Scraper made of 1095 Blue Steel

For four functions:

  • Touching up details on Prints
  • Preventing curling or warping of ABS or PLA prints (Raftless printing? YES)
  • Sealing holes or cracks to make a water-tight print (who doesn’t love to go boating?)
  • Instead of printing something big, print it in pieces and glue it together!

You can see the Makeraser in action on their new Kickstarter project page and snag one. Earlybird specials are still available at $30 a pop ($10 to ship outside the US.) They’re also selling a special liquid called Makelastic with the campaign to plasticize your printed parts, making materials like PLA super flexible. It’s an astounding print and dip solution that comes in at a steeper price of $70 ($30 to ship outside the US.) You can however get both the Makeraser and Makelastic for a solid $99, for a 3D printer accessory set your local maker space buddies will be jealous of.
