Make models that actually print: hollow planter, flexi ring and twisted vase

These are the tools in twyk that exist because a model has to print: a hollow planter with a drain hole, a rolled rim with Lip, the best face down with Lay flat, a part too tall for your printer cut in two, print-in-place gaps, a flexi ring tested before you print it, a sculpted figure and a twisted vase. Every tool shows a live preview before you apply it, and everything can be undone.

What you will make

  • A hollow planter with a drain hole
  • A print-in-place part with checked gaps
  • A flexi ring tested before printing
  • A sculpted figure and a twisted vase

Step by step

  1. Hollow and drain holes

    Make a planter hollow with a drain hole. Hollow shows a live preview before you apply it.

  2. Lip: a rim

    Roll a rim around the opening with Lip, for a planter that looks finished.

  3. Lay flat

    Let Lay flat choose the best face to put down on the plate.

  4. Cut, and X-ray

    Cut a part that is too tall for your printer into pieces, and use X-ray to see inside and edit hidden parts.

  5. Gaps: print-in-place

    Check that moving parts have enough clearance. Gaps finds parts that touch or sit too close to print apart.

  6. Repeat in a ring, and Flex

    Repeat a link around a ring, then run the flex test to see whether the ring springs back, stays bent or snaps in PLA, PETG or TPU.

  7. Sculpt

    Melt and smooth shapes together like clay to make an organic figure.

  8. Bend: twist, bend, taper

    Twist, bend or taper a shape, here turning a plain vase into a twisted one.

  9. Before you print

    A checklist to run on every model before you send it to the printer.

Frequently asked questions

What does the flex test do?

It checks whether a flexible part springs back, stays bent or snaps, in PLA, PETG or TPU, so you find out before you print.

What is a print-in-place design?

A design with moving parts that prints already assembled. The parts need a small clearance to print apart, and the Gaps tool finds any that touch or sit too close.

Can twyk cut a model that is too big for my printer?

Yes. Cut splits a model into pieces that fit, and X-ray lets you see inside to place the cut.

Can I undo a tool I applied?

Yes. Every tool shows a live preview first, and everything can be undone. Undo goes back about 60 steps and survives a reload.
