Build a 3D-printed injection mold

The V5.1 teaching model from the video, as printable files. A dry, hand operated mold you assemble on the bench to see how a fixed half, a moving half and an ejector system work against each other.

  • 25 print designs, 45 installed printed pieces, 35 screws and 35 threaded inserts
  • Closed it measures 148 x 118 x 148 mm, about 5.8 inches a side
  • No press, no material and no molten plastic. It is a dry model

Everything you need to print the model and understand what it is doing

One archive, four things inside it. Nothing to install and nothing to buy.

Closed, on its printed display feet. The red ring centers the inlet, the blue pad is the manual ejector: push it and the three ejector pins lift the plaque 6 mm.
The V5 teaching mold open on a bench, the moving half on the left showing the cavity insert and four black return pins, the fixed half on the right showing the flat face insert with the centered sprue hole, and the molded plaque loose in front
Open. Left, the moving half with the cavity and the four return pins. Right, the fixed half with the flat face and the centered sprue. In front, the molded plaque and the fit test coupon.
01

STEP and STL files

All 25 print designs, as the full assembly and as individual parts. STEP to open and edit, print oriented STL to slice straight away.

02

The 27 page assembly guide

Every part named and pictured, the A half and B half build order, and the check to run before moving to the next step.

03

Bill of materials

The 35 screws and 35 threaded inserts you have to buy, with sizes and where each one goes, as a spreadsheet and a CSV.

04

Print settings

PLA or PETG, 0.4 mm nozzle, 0.2 mm layers, 160 mm bed. The four return springs are the exception: those want SLS nylon.

Printing a mold teaches you the mechanism. Cutting one teaches you the cost.

When the part stops being a teaching model and has to come out of steel by the thousand, send us the CAD. You get tooling and piece pricing back, along with the design changes that lower defect risk before anything gets machined.
