3D model description

The Reaper

This is a open pour mold for a Reaper soft plastic fishing lure. The reaper is a leech type bait that has been around since the 1960's. This one was modeled after some old ones I have had since the early 90's.

I printed this mold in PLA+ and try to pour my Plastisol at or around 300°. (I use Dead On Plastix's brand of Plastisol)

Video of this mold's design and use can be seen at

I do not know the longevity of a printed mold. Your results may vary depending on brand/type of filament used. The mold we eventually warp over time from continued use... when this happens I just put the mold back on the heated printer bed for about 5-10 minutes and it will flatten back out.

I uploaded 3 different sized molds that should fit a variety of printer beds sizes. The baits are all the same the molds just have either 1,3, or 5 cavities for pouring.

The largest 5 cavity mold requires a 5" x 6" bed area to print.

4/16/20 - Per request I added master mold for the 5 cavity for creating molds from silicone. (I have net tested this so if there are problems let me know.)

If there are any problems with the STL's or you have questions please let me know.

Even if you purchased these files that Copyright means you are NOT allowed to sell the model or any derivative of the model for economic or financial gain. For example, you cannot sell the digital model, a derivative or adaptation of that model, nor can you sell prints of the model. I do however grant permission for persons who purchase any soft bait molds to sell the rubber soft baits you make with one of my printed soft bait molds.... but again you CAN NOT sell the actual models of the baits.
