Oil from cooking was splashing to the spice rack on the right and the bottle rack on the top left, so I created full length splash guards reusing packaging from Amazon and wrapped in aluminium foil. The attachment mounts were 3D printed. The top mount magnetically attaches to the rangehood.

I recently installed a sliding door in the main bedroom to ensuite.
I designed a door handle and lock combination.

Features: Magnetic hold in the open position and lock status indicator. The lock also pulls the door towards it reducing movement.

I have included the step files as dimensions of each system will vary depending on the set up.

3D Printed items from my son's 1st birthday party.

On the back end of Easter and Rabbit themed party, items included:
1. Creality Rabbit, 2. Spiral Egg by JamesThePrinter - both were Easter egg hunt surprise item.
3. Cute bunny bowl by AndrzejG - used to hold lollies & chocolate.
4. Dragon Egg by Tony Youngblood - a prize for a Quiz, containing chocolate.
5. Kendama by strshp - Kendama is a Japanese skill toy with a ball and cups, challenging players to catch the ball on cups and spikes. I remixed this design with a pokeball as the ball. This was a competition with the guests with each coloured cup scoring points and the winner winning the Kendama as the prize.

Note: the word Samuel and the vegetables were not 3D printed and was part of a cake - made with fondant - no layer lines :)

A fully 3d printed scale model of a Geodesic Dome structure. This structure has been used in playgrounds, greenhouses and even residential properties. I would like to explore this design more in the future.

Follow up post on the Wardrobe - Buying existing product and 3D Design Layout.

As a fully custom installation can be expensive and time consuming, I purchased Temple & Webster chest drawers. A quick 3D model was put into place, materials and colours applied and finally a render was created.

It is starting to take shape. The next step is to assemble the drawers and then judge how much the shelf position has to be adjusted up.

Wardrobe Renovation - a request from wifey

Problem identification - the wardrobe that came with our new home (2018) is basic. As it only has clothes hanging by two bars, we had to add inserts for clothes and delicates that are folded. It has also exceeded capacity where clothes are starting to pile up on the floor. This is also a fully open design so dust can gather on our clothes. Finally the clothes on the right hand corner is difficult to access.

Ideas - an idea comes from the mind, visualising how the current wardrobe is being used and it’s shortcomings as well as opportunities and how better to utilise the given space. This calls for 3 dimensional thinking - vertical, horizontal, depth.

Concept - a concept is translating your idea on paper or an iPad in my case. Using digital tools has truly accelerated the development process. I almost always take the photo of the current situation then overlay my concept using mark up. Always draw on inspiration from others (google images, Pinterest) - Toyota calls it yokonarabi or benchmarking. This allows you to see what kind of functionality you are after and what is possible. Once a concept is finished you can use this image to discuss with your client (wife) about her opinions and feedback. Once agreed we can do actual measurements to make any adjustments then proceed to create a quick 3D model of the design.

The following posts will look into the 3D modeling, cost estimate, bill of materials and build.
