Intro

A friend of mine had complained about loosing those silly little caps from his Nissin callipers and then faced the issue of not having them fitted ie. seized calliper pins.

Design

A quick potter about the workshops  looking for a loose calliper and I found the part I wanted on the NSR250 MC28 as I popped in for a brew.
A short while later I had it measured as an M10/1mm and 15 minutes later I had finished my brew and the printer was making some noise. I could have had them done quicker but first time round I wanted to add the dimple in the middle of the slot which I quickly binned to add strength.

I made them long at first to add some meat but was the over hang just makes them look loose so I cut them a bit shorter. 


 With the length about right I was basically done. Printing in CF PETg for heat dissipation, I changed to PETg as I didn't want to cause difference metal corrosion (yes carbon is in that chart). This however was a bit soft for my liking so went with ASA. Thankfully the Galaxy black I have is a near perfect match for the black powder coat.
I knew these would be a bugger for cross threading as the standard steel covers are bad enough but these were far worse than I would have liked.
I figured out I had not cut the thread through the bottom chamfer  which was binding up the thread making the part twist. Fixing this and printing upside down got me to a pretty damn good part. Amazing how much faff you can have when you are unsatisfied with just okay from what is, in itself, a compromise part. 

Looking good.

However we will start a little before that just in case you are reading this whilst trying to decide what to buy. We have also peppered in a few suggestions on where to find items you will need with links or suggested brands in orange . Considerations before buying You are going to need to know  what things  (tools)  you intend to put in this container and how deep the foam will need to be for those things to sit flat. Remember, different depth foam requires different length base plates. fig 2.1 20,30,50mm base plates Different foam colours can be used to help tool organisation.

1.1 Mighty small handle 3D drawing. Contents A)    Intro - About the mighty small handle B)   Fitting guide A)   Intro - About the mighty small handle 1.1 HPE Folding Tool kit handle CP PETg After the success of our folding tool kit handles, we decided we needed to go bigger, by going smaller.    The idea was pretty simple; make a handle for smaller shadow foam shelves that could be removed from  from a larger kit  to enable small items to be brought closer to the work area whilst still keeping things organised.  Design Key elements were: They have to be very compact. Light weight. Be easy to use. be strong enough to support a wide range of tools. fig 2.2 testing After some testing a final design was chosen with a base size taking up 40mm X 15mm of space each. Not bad at all! Stress testing was carried out till we ran out of things to hand off of our test handle, ending up with an  8kg per handle load,  a FoS (Factor of Safety) of 5. That is way more than is needed for this tiny littl

Yamaha FZ600 Chain Guide Swingarm Protector

  Yamaha FZ600 Chain Guide Swingarm Protector fig1.1 - HPE chain guide for Yamaha FZ600 Intro We have produced two chain guides / swingarm guards for the Yamaha FZ600 and early FZ400. We have a hard-wearing version in nylon and a TPU version which is more like the traditional rubber. This takes best advantage of an FDM 3D printer by producing a part in small batches to match the rarity of your motorcycle whilst also making them lighter than the OEM part.  The chain guide features increased wall thickness to allow the already highly wear-resistant material to last even longer. We expect the TPU part not to be as hard-wearing as the Nylon but it has the advantage of being cheaper and much easier to fit.  It is worthy of note however; that a poorly adjusted, unlubricated and/or rusty chain will make short work of eating through any chain guide. Fitting Guide The HPE TPU FZ600 chain guide will fit and remove in the same way as the OEM part, as it can flex and stretch into place without th
