Manipulate your 3D models with drag, rotate, and zoom tools. Pick your 3D printer and tweak slicing settings for perfect prints. Review results like fill patterns, supports, and layer details.

Key Features Include:
- Support for 43 FDM 3D printers (with the option to download over 400 printer profiles)
- Capability to load STL and OBJ files
- Customizable pre/post printing G-Code commands tailored to your specific printer
- Modification of default printer settings to suit your needs
- Direct upload of your G-code file to your Octoprint or Moonraker/Fluidd server

- Ask user permission before opening an external link
- Left Dock has grown up into an elaborate toolbox placed at left bottom, which display/modifies object unit, position, euler angles, scale, rotation modes 3.23 02/07/2023 - Fix slice flickering, which has happened as soon as any slice type has been disabled 3.22 01/31/2023 - First version with two finger TouchPad support. For object modification need to press OPTION-Key, too.
- Unlimited undo with redo
- Optimized memory management to free up memory for older devices
- While resizing the 3D view screen updates are suppressed to avoid memory usage spikes on some devices
- change layout of PlayControlView
- Deselecting an object is now faster
- Allow multiple files to be imported at once
- Auto resize of loaded files being too large or too small (within three powers of ten)
- replace buggy iOS UIDocumentFilePicker with iOS UIDocumentBrowser 3.21 01/30/2023 - further speed up of slice view, again mainly targetting devices with A9/A10 chip
- disable snapshot button, while slicing is ongoing
- for slice print simulation and play position at e.g. 10h with a slow speed factor like x0.01, the play position has not advanced anymore 3.20 01/17/2023 - Print Object dimension output as floating point and not as integer
- As per twitter feedback: fix load of files with 1 Mio+ triangles
- Improve reliability of print object selection per tap on older devices
- Increase timeout for slicer engine in order to support larger files 3.19 01/16/2023 - print object: out of print bed red shading is now along the boundary and not triangle based
- reduced startup time due to parallel shader compilation
- speed up of print object loading with nearly one million triangles 3.18 01/10/2023 - faster compute GPU algorithm - mainly for older devices - so that part loading for large parts is noticeable faster
- add missing update of the view on slice filter selection
- reduce memory usage

- fix transparent black printbed on printer change, if camera is below printbed
- increase printbed negative z as depth resolution of 32 bit float is at its limit
- adjust camera clip planes dynamically. This avoid slice flickering due to depth resolution limitation. 3.15 01/02/2023 - Process Configuration: Sections can be collapsed

- Complete rework of slice presentation in order to show sliced model in full at once 3.12 12/22/2022 - Fix startup error for older iPads/iPhones (Apple3/4/5 GPU family, perhaps Apple6 GPU family - means A9-A12, perhaps A13): "Encountered unlowered function call to air.simd_min.u.i32". 3.11 12/20/2022 This is our Xmas iceberg release. Only 10% of the changes are user visible...

Here is our (most likely not) complete list of user visible changes:
- Pan mode: in lower part of 3D view, panning will perform rotation around z-axes
- Object movement is now done with two finger pan
- Display rotation axes for selected object
- Select fixed/automatic rotation axes mode via left dock button submenu
- View rotation is not limited for eye point to stay above the print bed. Printbed is transparent, if viewed from the bottom
- Night sky rotation has been corrected.
- Stars of night sky are based on the Bright Star Catalogue (9096 stars). Correctness not tested due to lack of astronomer in the team.
- Allow timeslider to be selectable, which works in iPhone safe area and iPad with keyboard/touchpad
- iPhone: extend into safe area of screen
- Printer upload provides error feedback, if print server could not be reached
- Initial view by double tap is better adjusted to actual print bed/print object size
- Faster placement of new print objects
- disable import, as soon as any print object is outside the allowed print bed area
- finally welcome/onboarding screen, which may be used to announce changes in subsequent releases
- limit movement of print object within allowed print bed area
- Toggle between two different camera positions on double tap
- pixelated forbidden area for round print bed resolved
- iPhone: solved too small gcode view in portrait mode 3.10 12/19/2022
